If we keep 16, I would be legitimately happy with RHJ as our pick. Obviously he needs to work on his shooting, but he would have an immediate effect and would fit in well with the culture that is being created in Boston right now. If Crowder leaves, the choice becomes even more obvious in my opinion.
But, it seems likely that we are going to make a deal using at least the 16 - if we can use 28, 33, and/or 45 to move up into the low 20s, we should still have the opportunity to grab him - which would be even more awesome.
