I'd equate this situation more to Taylor Martinez and Adrian Martinez
Tommie Frazier showed up in late July 1992 to a room that included senior Mike Grant. He didn't play extensively until late October, in an Oct. 24 start at Missouri.
Taylor Martinez spent 2009 as a scout team wide receiver, then spent spring 2010 battling Zac Lee for the starting quarterback spot. He won it and was ready to show off his running ability in the opening, at home against an overmatched foe, Western Kentucky. He was great until a twisted ankle against Mizzou sent that season into a different, yet still successful, orbit.
Adrian Martinez came in spring 2018 to be the starting quarterback, and the goal was for him to get his feet wet against Akron and iron out the problems before the game against Colorado at home. Well, a thunderstorm and a malevolent twist from a CU defensive linemen sent that plan — and the season — spiraling. When he did return, against Michigan and Wisconsin, he wasn't good enough to overcome the injury, as well as make up for the overall lack of talent and coaching on that team.
Dylan Raiola, like the Martinez "brothers," will have a spring to get ready for a slate of home games to open the season, lifting the lid against what should be an overmatched opponent, UTEP. Colorado is the second home game scheduled. But there's no Michigan or Wisconsin coming up on next year's schedule until we face Ohio State in our eighth game. Plenty of time to work out the kinks. I'm not predicting we'll win all seven, but we should be in much shape than we were in 2018 after seven games (1-6).
