Connected franchise commissioner help

Hey guys I'm new to the online connected franchise. I'm trying to start a league with some of my friends. We haven't done the fantasy draft yet, and only 2 teams have joined. The other player chose the wrong option (he chose player rather than coach). Is there any way for either him or me to delete his current team and get him singed up again like he is supposed to be? Can't find any help anywhere, so any would be appreciated.
