There is no way he is lasting that long. I think there is about a 20% chance at best he lasts until the Packers pick. He is probably the #2 pass rusher. Tim Williams from Alabama is a great pass rusher - clearly more talented - but he has been in trouble and my gut feeling is his floor is a lot lower.
TJ is a Watt, so you know he's going to work hard and be a good locker room guy. While his ceiling may be less high than a Tim Williams, I think his floor is a lot higher. I like him a lot.
