My vote is Mundt over Hemmingway if they're only keeping 3 (and unless Hemmingway is an absolute blocking demon -- which I didn't look at). The thing I like about Mundt (unlike Hemmingway) is that when he's thrown a catchable ball --ta da!-- he catches it.
And a little farther-fetched... if New Orleans thinks they can slip their TE Arnold onto the practice squad, I'd be thrilled if the Rams grabbed him. He's got size, goods speed and good hands.
