Coach of defense wanted to put the DP in for the Flex(F1), and have the flex move to F7 and F7 to the bench. I know that the DP and Flex can both play defense at the same time but I thought only if DP is playing defense for player other than flex. I let the coach put DP in for flex but had him substitute for F7 thus Flex left the game. Fed rule 3.3.6(e) says that if the DP plays defense for the flex, the flex is considered to have left the game. I guess I need some clarification because I was told I screwed up.
