He is as good as gone. When you turn down ULL to play for Valley, get redshirted and then can't see the field because they wanna stick with a QB with a career completion % of around 47%, I throw my hands up on that situation (The RB Johnson (who turned down SC) also got redshirted and slowly has seen his carries increase starting with the Alcorn game).
As far as Southern is concerned, at least they are giving two QBs a look. With Skelton, there is a ceiling that I pointed out last year. He can run (same as our QB) but to get to the next level, McDaniel has to be that guy. Same thing with Grambling (although they do run it well). When you can get that QB who can throw for at least a 60% rate AND run like Harper, you stand a great chance of winning the SWAC
