I've got the exact same problem haha. Decided to roll with Allen today and tomorrow to see what he's capable of with a more consistent role. But the way it looks, he's in a time share with okafor, so we're all looking at all three, Allen, okafor, and boban (if dj gets traded), getting roughly 20ish minutes each. So this decision is looking harder and harder every day. They all look to have very good per-36 numbers even with small sample sizes. Imo, Allen is going to be the safest cuz he is the most mobile of the three so he is the best fit for the small ball type teams (although bkn can also opt to play rhj at the C spot). It's super hard to tell rn because boban has yet to play a game in LA and dj hasn't been moved yet, and Allen and okafor have just started their new minutes distribution. I guess the best thing to do is to have at least one of em and observe for now and grab the best one after all the dust settles (if they're even available) and hope u grabbed the right one haha. But in terms of needs, Allen is the best bet for blocks, okafor, for points, and boban for the %'s I would think.
Please keep adding so can all share thoughts on these guys and make the beat the best decision together haha
