I see so many teams signing their best players year after year (you telling me Bob Kraft isn't paying some luxury tax to the NFL for signing Brady to another extension)...what about the Steelers (Big Ben, L. Bell, WR's etc), the Broncos (with Manning, Von Miller, D. Thomas). The list goes on and on of teams that are paying a luxury tax because they go over the salary cap. The article I read awhile ago said the owners approved a bastardized version of the NBA and MLB luxury tax, so why not go ahead and spend money on our good players to retain them and to attract bigger stars.
The rule is in place for a reason...pay a little tax if you go over the cap and, in exchange, you get good players.
