What WR gets subbed in for RB in Trips if you dont have a RB?

Good question.
If you have no rb check into converting one of the other positions. The system will allow you to look at what the new numbers will be before you finalize it. If you don't like the results then don't do it. BUT- The converted player's WE undoubtedly will go up - If he's a freshman.
If you don't go the conversion route, then please let us know which position subs for the missing rb ?

I will find out after we start recruiting and get some exhibition games scheduled. I will report back my findings.
