Ok, I took a gander and I can change the roster to be set up more to reflect what Kevin accurately pointed out.
I'm somewhat inclined to do just that so that the rosters look like this:
Active/Starting:
2 C
2 LW
2 RW
4 Def
1 G
Bench (5 positions, you can set them how you like but it would reflect one for each position).
Alternately I could add a third goalie position and hence a round in the draft. That may be the best option, leaving everyone with two full lines (LW-C-RW-D-D-G) and a full set of spares.
Thoughts?
