I heard the perfect summary of the non Top 5 QBs on a podcast with Evan Lazar as a guest. They are all a bunch of Jarrett Stidham's. They all have limitations, warts, and blemishes and have a long way to go to become competent NFL QBs. I forgot whose podcast he was on, but the point was if they DON'T get one of the Top 5 (Top 4 really, as they didn't feel Jones was in the same class as the others), then they are just wasting a pick. Essentially, Stidham with two years in the system would be more productive than starting over with another project that would have to be developed and would be where Stidham is now in two years.
That made sense to me, as they suggested the likely career path for the Day 2 and 3 guys in this class was as NFL backups. Lazar is not just some blowhard talking head media type . . . he actually watched tape on all the QBs and posted his analysis of all of them.
His opinion was that if they can't swing a trade up for one of the main rookies, they would be better off using their picks to continue to build up the talent and depth on the roster and either see who might become available between the draft and training camp as a better stop gap for this year and / or try again next year when there might be more cuts / free agents, trade options, or guys available in the draft. As for talk that next year's draft is said to be a week crop of QBs, remember that at the start of this season, Wilson and Jones were not slated to be hot commodities like they are now . . . so there could be guys that emerge.
Again, it seemed logical to me to see if maybe Watson, Ryan, Garoppolo, Bridgewater, etc. might become available if they come up short on the Big 4/5 rookies. Maybe they have a higher grade on one of the Day 2/3 QBs and feel they can work with one of them, but I am not convinced after so many QBs have come off the board that there will be a legit QB with franchise upside still available. The only QBs not named Brady that were drafted as the 6th QB or later in the last 20 drafts that amounted to much of anything were Dak Prescott, Russell Wilson, and Kirk Cousins. Maybe there is a guy this year like one of them, but I think the chances are slim.
