In exchange for draft picks.  But again, it's false to say that no one wanted him AT ALL like you are.  Obviously at least one team did (Denver), since we snapped him up within hours once he was a free agent unencumbered by that massive contract.  And I betcha a number of other teams would have done the same if/when ready for an experiences backup QB like Denver was.  

You don't need to sell me on the stupidity of the Browns, BTW.  That whole move made no sense to me.  I get that they had like 100 million in cap money (how that's even possible is head-shaking in itself), but converting 16M of it to acquire a 2nd round pick just strikes me as a really bad deal.  Hell, go out in free agency and but 16M worth of talent.

But it is the Browns. There's a reason they suck so bad.
