Charlie Strong will do just fine at South Florida. People forget what he did at Louisville. He's coached in Florida (at UF) for more than a dozen years. He'll be fine and will likely be at USF for many years to come.
Sounds like they got some issues to work out with that new up-tempo offense because going 3-19 on 3rd down conversions against SJ State is not getting it done. They did run over 100 plays on offense
