Actually, the starters aren't closing out the games, they finish with CJ in place of Bell. But I have read that Jerry and the coaching staff want to keep CJ coming off the bench as they want at least one player in the second unit who can score. I don't think swapping CJ and AK for the opening tip solves the early-game woes.
The first unit racked up 41 points in the opening quarter against Toronto, and led 27-23 against OKC after one quarter, so I don't think it's a personnel thing. I think they just don't seem to run the offence with any urgency early on. Against Toronto and OKC they ran and got easy buckets IIRR, but in other games Deron has been walking it up, and the rest of the team has followed suit and been slow - even lazy - with their cuts. We need to start running and playing with urgency from the opening tip, not waiting until we're 18 points down and then playing like it matters.
