I am taking it you mean from this team.
I think Walker doesn't start over Hodge just to keep him fresh, and from hitting the 'freshman wall', so he can spell Calathes and run the offense. Because Hodge is inferior at point and someone has to give 'Wonderboy' a breather. Or be ready to step in if officials sit him down (UT game, our only loss by more than a couple points).
Anyways, here's what I think, you go BIG with the lineup...
Calathes, Parsons, Werner, Tyus, Chaney. Yes, I know Chaney's hurt. But he's better than Kadji, and why can't I make him healthy in my dream?
Needless to say, this lineup would struggle from 3's, unless Chandler gets his groove back. But I think having that much height on the floor would mean Chandler could concentrate just on his shooting ('shooting guard'

and it would come around. Also, playing Werner with Tyus and Chaney could mean he doesn't have to force himself to be as physical, and concentrate on his offensive talents (he is capable of passing well and shooting well, there is a reason he was the highest touted recruit of that lost class). We seem to both agree that Tyus is a 4, and both of our suggestions take more advantage of his jumper.
I also think a big issue with our current lineup is that we have Hodge (undersized, which puts a ceiling on his D) with Calathes (not particularly fast, though great size) to defend the athletic guards SEC teams always seem to have. Walker is better than Hodge, but still small and could lead to the same problems. Parsons is too slight to play down low, but would be a huge matchup problem with this lineup.
Anyways, next year I think we go with this lineup:
Calathes, Boynton, Werner, Tyus, Chaney
I think Chaney emerges as our best post player. He's more suited to the low post than Tyus. But Macklin could also be the answer here, he's certainly more experienced.
