He will be offered with the biggest salary in the league so he will stay, I think Toronto can give that since they really appreciate this achievement the team have made last season. Maybe let's look on the other teams and forget about Toronto for awhile as surely they'll be intact for the next season.
Then, it's exciting to see Toronto Raptors vs Golden State Warriors w/out injured players game on next season. Some Golden State Warriors fans here are still can't move on after Toronto Raptors won the championship.
Also for Kawhi Leonard, I don't think that money still matters for him, Kawhi Leonard is still young and he's not really into money unlike the other one goat from Los Angeles Lakers.
Nah Kawhi is kinda loyal if it wasn't because of misunderstanding in Spurs, Kawhi is probably still there. His aim is to become one of the greatest NBA player of all time. So Kawhi will probably stay at Raptors, as if Raptors will gave up this guy, the reason why they made up to NBA Finals and got a ring.
