This is just speculation on my part, but I think Darian Barnes was brought in here for one reason -- to create a tougher mentality and identity on offense. We couldn't swap out WRs, QBs, or offensive linemen, so we got a TOUGH player at a position we COULD swap out -- fullback. Answer me this -- when's the last time you saw ANY player on our offense barking at an opposing defense after a play like Barnes did yesterday? This has been a key missing ingredient from our offense for YEARS IMO. I don't think Barnes can change that singlehandedly, but I'm glad to see the front office is working on it. That's yet another benefit of having Randy Mueller -- if you've ever read his columns in ESPN.com "Insider," you'll know he thinks along these lines. I think he and Saban are going to be a great mix. Saban wants a tough, physical team, and Mueller is starting to get him the players for it.
