Wow, you are being a little bit too literal with the word rebuild, but I'll play along.
So if we continue with the construction related metaphor of rebuilding... We have a house with a bunch of bedrooms but no bathroom, no kitchen, etc. Those bedrooms work great, but at some point a person needs to use a bathroom, or the house is going be a mess. The person is needs a kitchen for it function well as a home. So, we have a house that needs major remodeling. It will probably take a minimum of two years to remodel since the local rules restrict us from remodeling more than 1 or 2 rooms a year.
I'm not sure what you are talking about. Assuming Hewitt is fired after the season this is the roster a new coach will be working with (also assuming no one transfers, which of course some will but we won't know who so this is baseline)
PG Moore/Jackson
SG Holloway/Lockett?
SF Mayimba/Lockett/Jackson
PF Jenkins/Royal
C Thompson/Porter
Graduating Copes, Gray, Edwards
So you are telling me our new coach can't figure out a way to make that roster work?
I submit again the players aren't really the problem.
