The Celtics have no shortage of big men on their roster. The trouble is that nearly all of them project more at the power forward spot than at NBA center. Fortunately for Boston the league has been shifting to smaller lineups and there are few dominant centers any more in this league (especially in the East) allowing the Celtics to sort of mix and match at the 4 and 5 spots. This is nothing new after Boston moved Kevin Garnett to center duties in each of the past two seasons.

In our panel vote rookie Kelly Olynyk landed a team-best 40 percent of the vote to start at center while Kris Humphries was next at 33.3 percent. Brandon Bass Vitor Faverani and Jared Sullinger all landed votes as well but were distant finishers.

With all the new faces it's likely that the center position won't be determined until training camp when coach Brad Stevens can mix and match his personnel and get a sense of who fits best together (remember Stevens puts a high value on lineup combos that work well together). Boston's versatility will allow it to go small at times and put a Jeff Green/Gerald Wallace combo at the 3-4 spots leaving a need for just one big (in that situation maybe Humphries makes most sense given his rebounding talents).

While Celtics president of basketball operations Danny Ainge has tempered expectations on rookie Olynyk by suggesting that he's pegged as a complementary role player his scorching summer league debut could eventually help him earn consideration at center in lineups where Bass or Sullinger play the 4. That allows Boston to mask Olynyk's rebounding deficiencies while also giving them some intriguing options on the offensive end.

And don't count out Faverani who has center size (6-foot-11 260 pounds). The question is whether he's ready to handle the physical nature of NBA frontcourts and that will be pretty obvious early in camp or exhibition play.

Olynyk or Faverani may very well ascend to that starting role during the season but the guess here is that Humphries is the starting center on opening night. You don't pay a player $12 million to sit on the bench. Boston would be well served if Humphries reestablished his value after a down year in Brooklyn giving the Celtics a potential trade chip later in the season (contenders would be intrigued by a consistent double-double presence if Humphries can regain his form). Obviously Boston's best interest is to give minutes to the younger players that will comprise its future core (Sullinger Olynyk Faverani) but spotlighting Humphries early could help the long-term future as well.
