the rest of the year and transferred in the offseason, that would be A VERY POSITIVE SIGN to the NFL scouts. Not only would it not be a red flag it would plus mark for Holker.
Transferring in and of itself doesn't raise a red flag. In fact, there was a lot of speculation of Jalen transferring before the 4 games were up that year. The fact that he stuck around was a great positive to any character questions that might come up. Nobody on the planet thought Jalen should stay another year to play behind Tua.
Comparing the Hurts situation to Holker just leads me to believe that you are not getting it.
