I've alway been an Alabama fan too and, even as a freshman, I thought Richardson was better than Ingram. As for the Cards taking him, they'd have to have a deal set up with another team to trade Wells unless reports are bad on the chances of Ryan Williams making a full recovery.
I've completely changed my philosophy on drafting RB's in early round 1 and now think it's a bad decision. They just don't last in the NFL anymore. It's hard to find a top back that isn't battling injuries, or has suffered a serious injury, every year. If you draft an OL, DL, QB, or DB and hit on the pick, you're likely going get 7-12 years out of the player. With a RB, you're lucky to get 5. Plus, it's become more of a passing league and 2 RB league and I just don't see the value in taking one in the upper half of round 1. Then , throw in the fact that most of the top RB's, Jones-Drew, McCoy, Rice, and Foster, weren't 1st rounders places even less emphasis on taking a RB early. I guess the earliest I would take a RB is about pick 25 and below.
