They have the following games left that should be highly likely to be wins (assuming decent health and they are not resting guys down the stretch). I'm not saying they are likely to lose some of these other games, but these should be double digit point spreads.
@Wizards, @Hornets, Pacers, Warriors, @Wizards, Wizards, Pistons, Cavs, @Nets, Nets, Hawks. That's 11 games. Let's estimate 10-1 on those. That gets them to 58-9.
As Tschmack says, they have a couple of very tough stretches, but they are 22-3 at home and the tougher home games are against the Thunder, Celtics, Heat, Grizzlies, Rockets, and Raptors. Let's go with a conservative 4-2 against that stretch (although they will favored in all 6 games). Now you are at 62-11.
The other 9 games are all tough road games. Three of them are the second night of just brutal back to backs. Let's say 3-6 in those games. That gets them to 65-17. That means the Raptors would have to go 23-2 in their 25 games to tie them.
1. @Raptors tomorrow on the second night of a back to back.
2. @Heat on March 2nd on the second night of a back to back
3. @Lakers on March 6th.
4. @Suns on March 8th
5. @Nuggets - second night of back to back and 3rd road game in 4 days.
6. @Mavs
7. @Raptors
8. @Celtics
9. @Sixers
