If TJ can play like TJ of old right away, then they finish very strong, since he fills a lot of holes on both sides of the court, provides leadership and toughness that is much needed, and allows for the role players to fill their roles more succesfully.
If he has trouble getting back on track, then this season is a bit of a write off as a team. I can see both Bosh
having beautiful numbers and the team struggling to get above the eighth seed. If they can't get to 6 or better than the playoffs will be tough.
