I'm zero percent worried about Stevens leaving town, honestly.
I'm 0% worried now. If Stevens leads another ragtag bunch to 45 wins and the second round next year, and Danny hasn't concretely moved our championship chances forward by getting a top 20 talent or two...then I'm worried. Like, 50% or more.
Why? Do you think Stevens will be uninterested in sticking around if he doesn't have a roster with multiple elite talents?
It's less about his interest in being here, and more about the type of offers he might get from other teams.
I mean, my scenario above is pretty far-fetched, so I'm not super-worried, but if Stevens pulls something like that off he will be one of the hottest commodities the NBA coaching world has seen in recent years.
If you're Stevens and you can leave to coach Anthony Davis, or the Bulls, or the Blazers, or Houston, at 2 times your current salary - why would you say no? Maybe at that point it would boil down to how much faith Stevens has in Ainge.
