I admit to getting annoyed at times by Fisto's posts, wondering why he seems negative so much of the time almost regardless of topic. But then I remind myself that it's just his style, and there are all sorts of styles here, and he just brings another ingredient to the overall blend of this place.
On the subject of Cobbs and sleepers in general, I think part of the disagreement as to whether such players are worth talking about or just a waste of time has to do with type of league.
On one extreme is a 10-team, 18-man roster, start two RB (or even start just one RB plus a flex) redraft league. With only 180 players and probably only 40 or so RBs rostered, drafting players like Cobbs isn't going to happen nearly as often. Still, I'd think owners would want to have some sleepers on their radar.
On the other extreme is a 14- or 16-team (I've even seen 32-team), 20- to 25-man roster (or more), start two RB plus two flex dynasty league. These rosters just are not stacked from top to bottom. When you're looking at 280+ rostered players, burying your head in the sand regarding possible sleeper RBs until they actually become starters will only guarantee someone else will own them by the time you are willing to pull the trigger, and you'll never, ever get one.
Five of my leagues are dynasty 14-team, 20-man rosters, and four of those can start up to four RBs. In such leagues the bottom of most rosters are sleepers and projects and role players, and owners are always looking to build a stronger team, year by year, replacing the crap at the bottom with guys with more potential. In one of those leagues, for example, I was a little quicker to see there was a chance Droughns might have a shot a couple of years ago so I grabbed him as a free agent (Droughns situation wasn't a lot different than Cobbs, nor was there any shortage of "Droughns sucks" naysayers). He's now been a starter for two years, going on three, and in a start-up-to-four RB league that's gold. And all it cost me was some backup kicker or low-stat, no-upside WR.
Droughns is just one RB example. How about Larry Johnson, Lamont Jordan, Rudi Johnson, Brian Westbrook, Domanick Davis, Willie Parker, Chester Taylor, Thomas Jones, Sam Gado, and other current starters, all of whom were available for next to nothing at one time but have benefitted owners who are on top of things. In fact, I remember the debate before the 2001 season as to whether Holmes or Richardson had the most value. Sounds pretty funny now, doesn't it? But Holmes had just left a team where he was a backup and had been an undrafted free agent. Some pedigree.
Any message boarder who simply says "he sucks" concerning Cobbs is in my opinion showing his own narrow-mindedness and ignorance of the facts since being picked up by Denver. There were plenty of "he sucks" posts regarding every name listed above before those RBs began putting up their stats too. To quote Fisto, "I want QBs who play 16 games, RBs who get 25 carries a game, and WRs that get 10 receptions a game." Well DUH, who doesn't. In a 280+ player league you're not going to find that, though, so what then do we do? Do we blindly ignore any player whose star value isn't already crystal clear? Not in large leagues if we want to be competitive in the long run, because there are a lot of other owners also searching for the next Holmes or Jordan. Are the odds great when it comes to guys like Cobbs? Of course not or they wouldn't be sleepers. The odds are zero though if we just sit there and do nothing, holding onto some trash WR or TE at the bottom of the roster, and let another owner reap the rewards when the sleeper comes through.
