I have a few thoughts and a theory:
o If you can't get a LT that you believe in, why bother.
o The D-line against the run was much worse than the O-line was rushing.
o Starting (2009) 2 rookies, a new center, a LT who had never taken a snap in an NFL game, injuries, etc., maybe
Nix and company figured the O-line Jauron fielded was such a mess it may be best to fix the D-line and see what if
anything the O-line actually has.
o D-line getting very old very fast, possible retirement of Schobel, 3-4 switch: let's use some draft picks.
Flame away.
