None of the guys you listed in the second paragraph are future NFL players other than X.
By saying that, then you are agreeing with my point that comparing Purdy's sophomore year and Dekkers's sophomore year is unfair to Dekkers.
My thoughts on the guys in the second paragraph are the same as for Dekkers. Their story isn't fully written and I am hopeful that during the rest of their time with ISU, they prove that they are future NFL players.
Call me a sunshine pumper if you want but there's no benefit for a fan like me or the players for getting down on Dekkers. Just like there wasn't the times I did it for Doxson, Bandauer, Rosenfels, Wallace, Flynn, Love, Terry, Meyer, Arnaud, Bates, Tiller, Jantz, Barnett, Richardson, Rohach, Lanning, Park, Kempt, Noland, and Purdy. I've seen the fruitlessness of my past way.
