I know there has been a lot of players that have learned from great talents while sitting on the bench waiting for their turn. How important/how much impact do you think it has?
Example I would say would be Aaron Rodgers behind Favre, Marlon brown learning from Steve Smith, michael vick helping foles etc.
I think this is a good question ( despite some of the responses that you've gotten in return. I am always amused at folks who say nothing but good things about FBGs and how the site has helped them win their leagues and win money, then proceed to behave in a way to drive off participation and subscribers.) in general.
From a team standpoint, I think you'll find, in the NFL, that as competition, there will tend to be a very neutral relationship between players at the same coveted positions. The guy you are helping directly, you are really giving him more knowledge and a larger skill set to take away your job. I think the nature of the NBA and MLB might be more forgiving, as they have stronger players unions and guaranteed contracts.
It's generally accepted around the league that Brett Favre went out of his way to extend his open hostility towards Aaron Rodgers. IIRC, it got to a point, where internally, some of the coaches reached out to Steve Young to talk to and help Rodgers understand how to survive as a high profile backup to legendary starter. I've personally heard some really ugly things that Favre said and did, and only see Favre's last season, limping in turmoil, injury and scandal, and with Rodgers winning a ring, to be a form of karma.
I think both situations are rare though, someone who is extremely invested in your career who is also your positional competition and someone who is openly hostile to the point where others will intervene.
I think where you will find the situation more likely would be Tony Richardson, on the back end of his career, older, and clearly just trying to hang onto the fringes of a roster, and realizing the fullback position was generally being phased out in most NFL offenses, who spent some time with the Jets and was seen as a positive force in John Connors early development. I think though you can't write that up to altruism, lots of veteran players on the edge of their careers realize coaching might be a future opportunity and want to show existing coaches and staff and front office personnel that they have the humility and ability to teach and handle younger players. I think this is probably the most likely scenario for a veteran player, already on the roster bubble, to reach out and help a young player despite the short term disincentive ( albeit with a potential long term upside)
Where I think you'll see more cause for increased development in younger players roots from
1) Improved and increased training opportunities in general at the youth level. Like I said before, when I lived in Texas for a while, the sheer volume of off season football camps and training opportunities was pretty impressive. High school QB1s in football factory areas could have easily been to a dozen specified training camps or programs outside of the traditional high school system.
2) Again, and I feel I'm one of the few people to cite this, the generational shift to having players now reaching the pro level who grew up in a booming video game culture. The degree and complexity of many of the current video game football simulations is staggering. There are kids who can't read but can decipher a Cover 2 in Madden football. And it applies to all roots of the game - roster management, injury management, substitutions, using the clock in 2 minute situations, running a hurry up offense, learning to read a fluid real time defense. These video games are essentially daily simulations that offer all kinds of scenarios and circumstances that build up a prospects arsenal of information about the game. As computer AI improves and becomes more realistic, it fosters a very real training scenario for those even at the youth football level. ( Again, these are the type of topics for articles that I feel Chase Stuart should be writing. )
3) High end training centers like the IMG Academy often bridge a players development from post draft to before training camp and sometimes during a players "offseason" away from the team. The speed of information and improved technology makes cataloging and watching film much easier than in the past. And given brands and sponsors trying to embed themselves early with athletes for endorsement purposes, the rise of brand specific training centers and academies are growing. Chris Weinke was not a good NFL QB1, but his experiences in a system not designed for the transition from college to pro helped him develop his program at IMG, where he made his mark being instrumental in helping to develop guys like Cam Newton. Making them full fledged Top 5 guys? Maybe not that, but helping with the transition points and acclimating to speed of the game.
The game has changed from players needing another job in the off season to help pay the bills. The job is now a year round full time investment for these players. There really is no true off season for these guys anymore. I would even wager that the current football system in place, from youth football in football factory environments to the cut throat Division 1 college ball to the pros, is more immersivee than even someone desiring a career as a physician in this country.
IMHO, I think when you hear about veteran players who are seen as positive forces in their locker room, I think it's more of a social dynamic where some Alpha Male players are able to control the tone and pace and temperament of their fellow players. Someone like Fred Jackson in Buffalo, who is beloved by his own team and coaches and respected around the league, I'm not sure he's in there every day with CJ Spiller, but I think his benefit is helping to foster a controlled positive environment for his team mates to thrive. Eddie DeBartolo classically said about Tim McKyer, before he dumped him, even with SF having CB woes then - I'd rather lose without him than win with him. There are just some players who are able to lead and galvanize other players by their base nature ( i.e. Jay Novacek, Ronnie Lott, John Offerdahl, Mike Singletary) and some who fracture a locker room as a whole.
I think in contemporary times, the most interesting examples of player development, i.e .a proxy for what you see as mentoring, come from Phil Jackson and Bill Parcells. Parcells was a genius at pushing buttons and waging psychological warfare on his own players. Notice the first thing he did in new digs was to ID two core players from the last regime, then brutally and publicly cut one and toss him to the street, and have the other stay and repeat the company line. Showing the contrast of what can and might happen to you if you stay or leave. Then infuse the locker room with his own "Parcells" players to regulate the tone and mood of the troops.
I think the core of player development is much longer standing process now. Football has really become a lifelong art within itself. I think the impact is greater than simply finding a veteran on the roster willing to help you if you reach the pro level. Just my take on it.
