Willis is literally living the sweet life in southern California's beautiful San Fernando valley.
Instead of playing behind Norton and McIntosh and doing school work he'll get to return in 2018 and be, at worst, the team's second best DT.
I used to think there was no way he was coming back, but after watching that video and reading your posts, I'm almost certain he'll be back. He's got that Miami look. Plus, it's pretty standard these days for troubled guys to leave school, move 3,000 miles away, work out privately with trainers for a year, and then come back.
I think it's merely a semester off from school/football. He can re-enroll for the spring semester and resume being a student-athlete in January with a healthy knee, rejuvenated mind, and some hype.
Granted, it's the best case scenario for a guy who could just as easily never come back to Miami again. However, they've been clear that this was a personal decision and that he wasn't booted, whereas they couldn't wait to announce that they'd kicked Courtel to the curb.
