Well, according to Tim Brewster he is.
OK, Bell was good (strike that - GREAT), but to say the best defensive player of all-time? Really? Put down the juice, Brew.
Even if Brewster meant "Greatest [Minnesota Golden Gopher] Defensive Player of All-Time", I still would call him on it. Hell, I'd put Bronko Nagurski ahead of Bell. Sure, he made his living on offense, but he was a beast on defense, as well.
One thing is for certain, Brewster is... uh... excited...
