Well, just like Brad Banks, maybe Minshew needs to go to Junior College and prove everyone wrong. If he truly desires to be an SEC QB, then by going to EMCC or another JC and performing, some SEC school will probably offer him.
One thing I do truly respect about Bo Wallace is that he knew what he wanted, he went to JC, and found a way to become an SEC QB and a somewhat successful one at that. Minshew will have the same opportunity.
In fact, sometimes I believe it's easier to become an SEC starting QB out of JUCO then it is by going to an SEC school out of high school.
Out of high school, you may be entering a situation where there are 4 or 5 other QBs on the roster that you will have to beat out. However, out of JUCO, someone is likely recruiting you to come in and either start or compete for the starting job.
