I was one who was disappointed Simpson left, mainly because of his defense and because I wanted more culture carry-over from year to year, and I thought he could help bring the younger guys along.
That said, his role would have pretty significantly changed, and I don't think he saw himself as a 7-8th man complementary piece playing 12-15 min/game with a dramatic reduction in shot attempts. It was pretty clear by the time he made his decision, that our starting guards would be Harper/Williams and that Davis would be staying to play with Bailey.
At the time he entered the portal on 3/18, Mag and Griffiths were also still on the team (they didn't enter the portal until 3/20 and 3/28). Woolfolk entered the portal the same day, and the only guy who jumped faster was Chol on 3/15. It was pretty clear Simpson wasn't looking to take a reduced role as a rising junior and was looking to transfer down somewhere he could have higher usage.
I'm glad he found a spot. On a "per 40 min" basis, he's contributing about the same to St. Joe's as he did for Rutgers last year, but more efficiently (though it's been against a far easier schedule). No ill will toward Simpson from my end. Would have loved to have him as a 10-15 min guy for his defense and FT shooting (and some opportunistic buckets on limited shots), but I doubt he'd have been happy in that role.
Had he stayed, though, it would have most likely been with Acuff's schollie not Davis'.
