A common misconception -- and one that I occasionally fall for -- is that in today's salary-capped NFL, the most successful teams are built primarily through the draft. That's not entirely true. The Patriots went on a spending bender this off-season, locking up Adalius Thomas, Wes Welker, Dante' Stallworth and Randy Moss (and every other available veteran wide receiver). Last year, the Ravens traded for quarterback Steve McNair, filling their biggest need; and in the two years before that, they inked cornerback Samari Rolle and wideout Derrick Mason to lucrative free-agent contracts.
