vince is not the shooting guard when the lineup is
1.harris
2. hayes
3. VC
and walter herman is not Detroit's SG.
Vince is the shooting guard in either line-up. Hassel and Hayes are both forwards and both are bigger and strongetr than Carter.
When Marburry was guarding Herrmann the line-up for Detroit was Prince-Brown-Bynum-Herrmann-McDyess. So, yes, Herrmann was the shooting guard in that line-up. Who else is Marbury going to guard in that line-up?
Doc can only work with the players he has healthy and on the bench.
