I also have hopes for Kaman. However, very frequently the Clippers design plays for him early in the first quarter. They'll need to rely on that more. If other teams watch tape, they'll be double teaming Kaman at the start of each half.
So he'll have to excel more in the "unscripted" aspects of the game: defense, offensive rebounding and putbacks. I think he can do it.
He's not the next Olajuwon, but he could easily be in the top five centers in the league. Probably never an all-star, but good enough for this team. (with the dearth of effective centers, he arguable already is one of the top five!)
