It is past time to make a decision. Continuing this rotation is sacrificing valuable practice reps and continuity as a starting unit.
For me, Bowman is the first out of the race. With even just a mediocre Oline, he’d probably be the best option. Unfortunately this veteran Oline is miserably bad, and Bowman not having the ability to move around puts him at the biggest disadvantage.
That leaves Gunnar and Rangel. Gunnar has the best point production after the two games so maybe the slight edge. Arguments could easily be made for Rangel as well. Just start one for S. Alabama, if the offense is stagnant, then give the other a shot to provide a spark.
