You know I'm a big UB booster, so I've seen every game Patterson played. The big knocks on him are his size, the fact he rarely got involved in the passing game and his middling speed. Also it's hard to separate how much of his success was thanks to his blocking, which was excellent.
That said he has excellent balance and can make people miss him in a phone booth. He also has a bit of the "Josh Allen disrespect" thing driving him. No D1 schools other then Buffalo offered him a scholarship. (Like another kid named Khalil Mack.)
I think going to the WFT is a great move. Not only is it his home town team, their RB room is not impressive. He's got a chance to stick there.
