Clinton McDonald - Best FA pick up?

Man, I know it's only pre-season, but what a surprise this guy has been. Him and McCoy have been absolutely dominant in the inside. Gotta give props to Licht for finding this gem and for getting him at such a cheap price. I really think he might be the best pickup of the off-season. Now if Michael Johnson lives up to his contract or Clayborn steps up his game, I have very little doubt that this will be a top 5 defense this year. We just need some pressure from the outside because our two monsters at DT are most definitely doing their part.
