What would burning Yates' redshirt have to do with recruiting? We already have a QB coming in next year and will be recruiting one for 2021 I assume.
Because other head coaches will be in the QB's living room saying that Geoff Collins will burn your redshirt and negatively impact your potential to play in the NFL it it helps him win 2 games instead of 1 in his first year at Tech (assuming we win another game). With this OL, it is stupid to try a true freshman that didn't win snaps in camp.
Or, CGC doesn't know how to manage redshirts, he started the season with 3 QBs, one got hurt, and he burned a QB's redshirt to move one of his QBs to WR in the middle of the season. Maybe he'd burn your redshirt in order to make a bowl, or some other reason, etc.
Or, CGC will process you to clear your 4 years of eligibility if you don't win the starting job in year 1.
Further, CGC says it is a player driven system. He evaluated T Oliver to be a QB for 10 months, then convinces himself that he's wrong, flips him to WR, and burns a kid's redshirt in the heat of the schedule instead of just managing the roster by playing A Brown, M Carter, A Sanders, J Blancato, O Jarrett, N Cottrell, J Hawkins-Anderson, etc at WR. Now, another head coach can say he cannot evaluate a QB, develop a QB, manage a roster, etc. You know they'll bring up that he is a defensive minded coach with a short head coaching resume to QB's. You can't hand them negative recruiting material.
If you think moving to T Oliver to WR is a good idea, then you do it next year. L Johnson as a 6th year with some game film, J Graham as a R-Sophomore with some game film, and J Yates as a R-Freshman with a year in the system, plus T Gleason works as a redshirt unless he's that good. T Oliver gets 2 years at WR and more KO returns to put plays on film for the NFL and you still use him as your wildcat QB to mix it up, also great for the NFL. Then if T Oliver can get on a 53-man roster as a WR / KO returner, CGC can say he successfully took a QB that couldn't beat out TQM or LJ as a starter and got him into the league making $570k as a 23 year old.
In general, it is a bad move to consider moving T Oliver to WR this season. The upside is essentially zero. This season is toast, but it has been since December 2018.
