Yeah, I'd say both are concerns. Our RBs are not monster RBs and even with Whit last year we were ranked in the bottom quarter. Now with perhaps a weaker OLine I'm not sure we'll improve at all.
Most of us remember that Tutu pick while that great center, (from Alabama) was still available. Didn't he become all-pro or all Rookie? Some of us felt that that poor pick would haunt us longer term. We'll see. (Sorry I am not a Tutu pick fan at all. While I hope he's great I thought the bigger need was OLine).
OTOH, McSnead have shown a remarkable ability to fix problems, unlike Jeff Fisher.
