When the Tampa Bay Buccaneers end their preseason schedule and days before they start the regular season, they'll have to make a whole lot of decisions on who to cut and who not to cut. Most of those cuts have already been decided -- despite the hype of training camp competition, realistically that's only true for the bottom of the roster, and even there many of them will still be replaced during the season.
But one factor is always a wild card: money. Teams love their cap space and hate paying too much for players, and that will come back in a big way at the end of training camp: people will be cut not because they're not good enough to play, but because they're too expensive.
