I'll buy that with Nelson but you can't blame the coaches for Floyd or John Brown. Floyd has an alcohol problem, I blasted the pick at the time because of his history in college and before and even I didn't expect his career to go the way it did, can't fault BA there he inherited that problem and since Floyd has moved on he's been a virtual non factor.
John Brown has a serious medical issue and if you go back and read the scouting reports on him in college it's apparent it existed even then, they just hadn't found it yet. he had a history of muscle pulls and crampiing in college, it was also there early in his Cards career. But since it got signficantly worse and we found out about the sickle cell issue, it's been apparent he's just not the same guy. That's not coaching it's just a guy whose body isn't letting him play at a high level anymore.
With Nelson I don't know what to think, I'm willing to put some blame on the coaches there, he's so inconsistent, you write him off and he suddenly has a string of games with TD catches, then you think he's turned the corner and he disappears for weeks at a time. Just seems like a guy who was being asked to do too much this year given his actual abilities and got exposed. I'd still like to keep him but he's a 3rd or 4th Wr he's been playing too much.
It also seems like losing Palmer hurt him more than any of the other Wr's.
