The move makes sense for the Browns considering that Williams had a bloated salary and gave little out-put in his two seasons with the club. Had he not been traded, he most likely would have been cut.
Williams came to the Browns in 2008 from the Green Bay Packers, where he was a fair pass rusher. However, he never came into his role in the 3-4 defense as an anchor of the line. When allowed to rush the quarterback he did well, recording two sacks in the Pittsburgh game.
The irony of this trade is that Phil Savage (then Cleveland's GM) traded a second round pick for Williams. So after two years with the Browns, Williams has turned from a second into a fifth round talent.
It must be noted that this was but one of the very poor moves made by Savage, leading to his dismissal at the close of the 2008 season.
The new regime of Holmgren and Heckert was lucky enough to get some value and make up for past mistakes.
The move still gives the Browns 11 draft picks, but now they have nine in the first five rounds.
