I think that is because Bustle enjoyed glorifying his senior roster over the underclassmen even though they arent as talented.
There were multiple examples of this and the most obvious were James Butler and Darryl Surgeant stuck behind the butterfinger receivers of Rico Joseph and Marlin Miller and never getting their true chances to produce ALL YEAR.
Also the very beginning of the season when they named Julian Shankle 4th best running back on the team STARTER just because he had previous experience.
If bustle had a deep roster that consisted of all classes he would go by Seniority first then talent, which is quite ignorant, but if we get a coach that looks on sole talent and productivity and forget about the grade of the player, then we will be able to put the best players on the field.
Thats just the way that i see it atleast
