Can anyone explain how he would fit in Stevens' system? Or is he just a big name that people are throwing out there and a bad fit?
Beyond the fact that CBS will definitely be willing to adjust for him, here's how i see it breaking down lineup-wise.
Offense: Surround Dwight with at least one (maybe 2) pick and roll ballhandler, add a stretch forward, and a shooter. Dwight rolls to the basket to finish or draw the defense in, leaving space for 2 options (shooter/stretch4) for an open bucket. The ballhandlers either drop it off to a rolling Dwight, find the open shooter, or score themselves.
This may seem simply explained, but no one on the team current is the rolling threat to finish as Dwight would be. That's why defenses would are more willing to hedge the ballhandler, rather than ICE-ing to take away the rolling man.
Defense: This is where Dwight's value is undeniable. Any lineup with any combination of Smart, Avery, Jae, Amir, or Dwight will be enough to make up for the weaker defensive players on the team like IT4. As long as at least 3 of those guys are on the court at all times, the defense has at least 2 perimeter bulldogs and 1 legit rim protector. Subjectively, i assume that having at least 3 shutdown defenders for all 48 minutes is gonna be an issue with any team.
