Bill, I think I agree with you on Teague, as long as Preston is ready. While Teague has been steady for the most part he is still showing as a liability vs. inside blitzes. Anderson I think has played better than you are seeing, as most of Willis's bigger runs have gone through him, though he is showing some poor footwork at times vs. the pass rush. I can't say he's worse than Tucker. Gandy for the first time yesterday showed some lack of ability one on one vs. a good edge rusher. He has been solid run blocking though as well. His position could certainly be improved though he has played as well as can be expected. MW I think will be fine as long as he gets his butt on the field. The salary is a little high though I agree at this point, and he may have to restructure. Chris V I think is ok where he's at.
Disclaimer: I am waiting for the coaches to take advantage of the run blocking abilities of this line to give them a chance, which they haven't done. Until that time, a complete assessment cannot be made IMO.
