At the risk of being that guy, it will take everything to go the raptors' way to get into the playoffs.
1. Siakam has to get back to be pre-covid form. If he plays like last year, it will not bode well for them.
2. VanVleet needs to play near all-star level, and needs another (point) guard on the floor he can play off - he and Lowry were a potent combo because it was always random who played PG and who played SG on every possession. Maybe Dragic (assuming he doesn't get waived/traded) will be ok for a bit. Maybe Trent will play more with the ball. Maybe Malachi Flynn will take a step up - at least one of these has to happen.
3. Scottie Barns needs to be able to play quality minutes. I admit I don't know much about him, but given his high draft position, he has to show something next year.
4. Anunoby needs to have another upward step in his game
5. Boucher/Birch need to somehow create a strong Centre, or the raptors need to somehow find a proper Centre (which all of a sudden has become really difficult since centres are back in NBA fashion thanks to Giannis Antetokounmpo and Anothony Davis both playing a lot inside, and Deandre Ayton's play (to a lesser extent)
