Jefferson's the low-post scorer, Millsap's the face-up guy who spends some time at small forward. I don't think that Biyombo's proven himself enough to be a building block yet, so I wouldn't plan on building the team based on how guys fit with him. I also think that pairing a 6'6" power forward with a 6'8" center is going to get you in trouble against any team that features real bigs. Also, Millsap's turning 28 this season, and part of what makes him so effective is his quickness and athleticism advantage against opposing power forwards. I wouldn't want to give him a long contract that stretches into his thirties. Flame away.
