The Tampa Bay Buccaneers signed Dallas Clark to a one-year deal worth $2.7 million, including $1 million in guaranteed money according to ESPN. Giving him $1 million in guaranteed money signals a commitment to Clark as an important part of the offense this season, and he should step in as an H-back/move tight end.
Those numbers mean that the Bucs didn't even save all that much money by trading Kellen Winslow to the Seattle Seahawks. Winslow was scheduled to earn $3.3 million in base salary, as well as a $550,000 roster bonus and a possible $500,000 in workout bonuses, all of which will be picked up by the Seahawks now.
Of course, the Bucs don't exactly have to mind their spending right now. The last salary cap update I can find comes from April 24, when ESPN reported the Bucs still had a massive $16.9 million of 2012 cap space available. The Bucs have done a very good job managing their contracts, but this move wasn't likely brought on by Winslow's salary, given the amount of money they're now paying Clark. Instead, production and possible a team fit appear to be the key motivators.
