I can't see Alzee coming back from that kind of injury and just being able to start right off the bat. There is no guarantee he will regain the same speed he had before surgery. My guess JJ will ease him back slowly , maybe 10-15 minutes a game until he can prove he is 100% healthy.
From what I've seen of Walton , he's not going to start.
If we do land Henry , he can move into the 3 and Williams can take over the 2 spot. Mitchell is good enough to play any position on the floor , but until he comes back our 5 position will be a question mark.
Give me : Jones,Williams,Henry,Holmen & Hogans until Mitchell is cleared. We won't have a true 5 , but there are not a lot of teams that could match up with this starting 5( 4 athletic guys all over 6'6). If Edwards can ever get his knee problems worked out he could replace Holmen.
Once Mitchell is cleared bring in Holmen off the bench
Just my thoughts
