When the cap keeps rising in 3-4 years, and max contracts become 35-40M/Year, then Whiteside's 25M/year will look like a bargain.
Not saying it should be their #1 option, as the Celtics should explore cheaper options out there too.
But would you pay Howard 30M/Year? Horford a Max? Maybe if KD likes Horford then yes but other then that no way.
Maybe Joakim Noah on a reasonable deal. But if we get Whiteside for the max I wouldn't be dissapointed at all. He fits the need of rebounding, interior scoring and rim protector that the Celtics sorely need. And if he can keep giving us 14/12/4 (4 blocks a game!) type numbers I'm perfectly fine, but Stevens can probably make him even better.
Also I find it funny the same people who call Whiteside a "nutcase" and "cancer" for this team would LOVE to get Cousins. Yes I get Cousins is 5x better than Whiteside but the double standards here are funny. Also he fits the defensive attitude of our team (guys like Smart, Crowder, etc.) and it doesn't hurt to have an instigator on this team (look at Draymond Green in GSW, or Dellavedova for Cleveland).
