Let's look at it the other way. In baseball one successful season is always questioned. Casey McGehee's break out year was followed by calls to trade him before he crashes. Yes, I know McGehee never had shown any signs of being great and he did dip (.859 OPS to .801) but it certainly wasn't the crash and burn many were expecting. Overall there sure are a lot of baseball players that have a great rookie or first few years and then completely drop off. To compare it to football, Arian Foster was a backup and practice squad player before this season and now leads the league in rushing. Adrian Peterson has a great first few games and has been a star since. I guess what I don't get is after one season of baseball you have much more information about a player than football. Spring Training, regular season and playoffs could add up to almost 200 games. With football you are looking at 24 tops. A lot of people pointed out quarterbacks who were given constant opportunities and I will give you that. I took a quick glance at the first round of the 2007 draft. There were some really good players in that first round (Calvin Johnson, Adrian Peterson, Patrick Willis, Darrelle Revis, Dwayne Bowe) but there were also some busts who are pretty much nobody's already after just three seasons (JaMarcus Russell, Ted Ginn, Jr., Justin Harrell, Brady Quinn, Greg Olsen, Anthony Gonzalez). To me it seems like in the NFL you get a year or twp tops (if you're not a QB) before your shot is over. In MLB guys make careers of off the word potential.
