Again the PJ Tucker at Center was a 1/2 season D'Antoni experiment.I agree--I understand the "PJ Tucker" archteype for being a big at his size, but I think Tucker is such an outlier it is much more likely that Grant succeeds in the way you describe. The passing, emerging 3Pt shooting, smarts and versatility at both ends (credible in the paint at both ends, can rebound, smart, strong core) are really useful off the bench if you pick up a half-step on the perimeter as a 3 or vs stretch 4s.
Not sure he can, or if team agrees, but I think worth a shot. Interesting that the TT signing makes more sense if the above is indeed the plan this year
PJ has primarily played as a perimeter 4 for his career. Thats how he is being used this season
