We will see, but I think absent injury Brennan starts day one and he has been the successor to Etling since he was second string last year.
I agree Orgeron will not announce a starter and pretend its a open competition.
I also do not think Ensminger will do a true 2 qb system. he might let another qb run a few wildcat plays, but it wont be alternating series or quarters in the regular season.
I think Brennan should be the starter. He has the best arm of the three and is the most accurate.
The real battle is for second string and I agree with you McMillen may be ahead of Narcisse.
