I was really only talking about Bryant staying as it would have related to his personal prospects for success in the NBA.
As it would have related to IU as a team last season, I actually think Bryant staying would have been good for the team overall, including Juwan. Bryant really would have been the perfect frontcourt pairing with Juwan. Having Bryant at the 5 would have allowed Juwan to slide back to his more natural position at the 4. And at the same time, with Bryant’s ability to get up and down the court and play on the perimeter, Juwan would still have had plenty of room to operate in the paint. I guess in that scenario, Juwan might not have developed quite as much because he wouldn’t have been counted on to basically carry the entire team, but he still would have been a key player for us. And the team likely would have been a lot better, and probably makes the tournament.
Now Davis would have been the odd man out in that scenario, but like you said, he might have also avoided injury. Smith would also have played a lot fewer minutes, but I don’t think bringing him along more slowly would have been a bad thing necessarily. Overall, Bryant staying would have been a good thing for all involved IMO.
