Good ideas, BGIM. I envision TD doing a good deal of shopping , come March FA. While he probably won't aquire any top $$ FA's, the depth concerns of the Bills could be upgraded , prior to Draft Day.
Re-signing Pat Williams and Marcus Price would be realistic. Then go shopping for more OL, TE's, RB's, #3 WR. Secondary and DL depth. Can't envision the Bills breaking the bank for a top LT. Maybe a Kicker or wait and draft Nugent. Maybe a QB, depending on the situation.
The off-season is always interesting with TD. He's very active in player movement.
