I'd like to see Taylor get very little work, actually. Same for Rex. Let's see the improvement Martinez has made in his footwork - or, at least, that it's improving, and put him on the sideline signalling in plays. Let Rex have one carry and bench him. We know what we have in those two, at least on the ground.
I want to see that Carnes has improved, and that we're not going to fall off a cliff if Martinez gets banged up again. I want to know (not just suspect) that AA and Green can carry the load if (God forbid) Rex gets hurt.
I want to know that the O Line has improved.
I want to see the D Line do something magical, and I want to see that carry over to the regular season. Last year Eric Martin knifed through the O Line like a hot knife through butter several times in the Spring Game, then largely disappeared in the regular season.
