You know, I'm not sure that the Bucks have as long of a shelf life as people seem to think. Giannis will be MVP-level for the foreseeable future, but the rest of the core is much older than he is and they're pretty tapped out on assets.
Giannis is 28, but:
- Middleton is 31 and has been really banged up in the last year
- Jrue is 32 and has also missed a bunch of time with injuries in the last 2 seasons
- Brook is having maybe the best year of his career but is 34 and had major back surgery in the last year.
There may be a point shortly where Giannis has to be superhuman to keep the Bucks near the top.
