See coaching pool $$. You have an OC\OL coach and I am pretty sure a DC\LB coach. When your coordinators are also position coach's, that is a problem.
You are not correct. Schools are limited to 10 on-field assistant coaches and UConn has 10. At most schools, the coordinators also coach a position group.
Let's look at the 4 schools in this year's playoff and look at the coaching responsibilities of their coordinators:
Alabama: DC/Inside Linebackers, OC/Quarterbacks
Clemson: DC/Linebackers, OC/Running Backs
Notre Dame: DC/Linebackers, OC/Quarterbacks
Ohio State: DC/Secondary, OC/Tight Ends
