To further expand on this...
In today's world a QB's redshirt will only matter if:
1. They are good enough to become QB1
2. They are never recruited over
3. They stay for a 5th year, never wanting to leave for another school or even the NFL Draft.
Is Carney good enough to eventually be QB1 (point #1)? If not, then who cares about a RS? Is he good enough to not be recruited over by someone from the 2026 or 2027 HS classes that Fran brings in (#2)? Or a portal QB for 2028 (also #2)? Will he be fine waiting until 2028 to be QB1, and/or never get homesick (#3)? If he is QB1 in 2028 will he be so good that he gets on Draft boards (also #3)? I doubt that one given his measurables.
So much has to happen for his RS to even come into play.
On top of that, playing more than 4 games as a true Frosh doesn't mean you cannot redshirt as a Soph or JR instead. What are the chances that Angeli will miss 5 games in 2026 and then miss 5 games again in 2027? Most likely QB2 will not be needed to the point that he cannot RS in 2026 or 2027.
IMO it is foolish to worry about a QB's RS when they can actually get legit playing time (ie not mop up duty).
If Carney has real potential, wouldn't he benefit from QB1 practice reps the last 8 weeks (6 games from Pitt on, 7 if we made a Bowl) of this season? If he doesn't have potential then he shouldn't play, in which case we shouldn't care anyway about his RS.
Again this is all assuming Collins vs SMU is the same Collins we saw vs Colgate and then vs Clemson and then vs Duke.
