There are certain things for sure to consider, at this junction you don't need to worry about meeting the promises. The rule is that you need to start at least 80% for the once you promised and by now you secured that part.

As far as the starters go, It's really tricky in your situation, but there are few things I would be sure of. You are pretty thin on the big men (PF/C) so you want to keep Coleman as backup for depth to Kenneday and Seay.

Also Wartburg SF is more like a SG with speed and perimeter, so especially because of that you want one of your smalls and not big at SF to better match up. But the real bottom line why I go with small at SF is because you are running Motion and you need good BH & Pass as well as speed. I personally would go with:

PG - Belford
SG - Ferguson
SF - Trapp or Coates
PF - Seay
C - Kennedy

I'm also not so high on Belford and Ferguson as they are pretty poor atheletes and defenders and you are running M2M, so I give them only slight edge over the other players. I'd definitely give significant backup role to Jeffery Anderson at PG/SG. Denn & Faber I don't like, they should be 3rd string backups.

Good Luck!
