I like those backs at the top of the draft as much as the next guy, but the realit is the Cards don't really need an every-down back. They've got Edge, who is one helluva grinder at this point in his career (I mean that as a compliment).He's got at least another couple years in him in that role, but he does need to be willing to give 10-15 touches to a back like Johnson.the guy is ultra-fast but i want the Cards to get a young RB that can be an everydown back.
If we can get a guy like Johnson in the second, I think our offense becomes very, very dangerous.
If we get a guy like Stewart, I think we need to cut Edge because he'd be repetative and I could see a situation where some angst builds in the backfield, whereas Johnson would compliment him very nicely.
