At this point I would not trade Allar for anyone's quarterback. I think he will be the best we have had all-time (though probably not in total yards/completions, given only 2 full seasons as a starter are likely). I think he will be sharing a bit more with Pribula too, which is good. Pribula looked ready to play -- especially running. He may be the man to run out the clock in the 4th.
In the past I don't think the starter would have been pulled when Pribula went in (ahead by 16), so I'm pleased that perhaps we see a need to develop and play the #2 with meaningful snaps.
Show me a PSU quarterback who had looked better than Allar, in terms of tools, vision, poise, mechanics, etc., at this point in his career. I can't think of one.
