I think BB has done a great job in saving at certain positions to spend elsewhere, while maintaining constant winning seasons. When Brady was throwing darts at players knees early in his career, they got by with what must have been the cheapest Oline around. Outside of Light, Woody and Koppen, they hardly spent anything. even Neal didn't blossom for a while so I doubt a wrestler commanded much of a paycheck.
They spent heavy on their three man line and it carried the team, especially as the LBs got old. Speaking of LBs, without high picks, and the polian rules, they spent on offense and cheaped out at LB, except for the misbegotten Adalius deal, in favor of offense (Maroney, Chad Jackson). Probably a mistake in personnel, but maybe in resorces. Hard to tell what would have happened had they spent those picks on LBs, DBs or D linemen.
Lately, they've been cheaping out on D line, leaning on Wilfork, until the
easley pick and stocking up on LBs and DE-OLB to good effect in the draft. DB depth and Revis Browner have completed a defense that's very young, with picks in LB and DB and good patches at D Line to go with a hopefully healthy easley.
Unlike the old days, with a mature Brady making al the thows, they are paying big on Oline in the future IMO, with young costly tackles, contract for cannon, assumed contract upon performance future for Stork and probably a future guard making more early than conelly wendell (just a guess). Priority being improvement to a great line to keep brady upright.
They aren't spending a lot on WR, RB which suits their team and game plan offense IMO, especially considering the jackpot they've hit at TE with Gronk and the surprising Wright.
