Can't say either of these moves are surprising. Stokely was expensive and never played. Reagor, if healthy, might be re-signed later on at a lower price. Either way, expect to see multiple D-Lineman taken in the draft.
I'd feel worse for Monte (his agent responded to his release by noting what a 'horrible business' the NFL is), but Reagor did have at least one thing go his way this season: Instead of being remembered forever by me and others as that "idiot aggresive driver who completely screwed an already questionable run defense by getting himself t-boned," after the Super Bowl victory he'll instead be remembered as "the poor guy who's unlucky accident cost him a chance to play in the Super Bowl."
