Go back and read you earlier post. You expressed concern about Tuttle because he transferred ("well, I think the fact that they transferred in the 1st place is a clue. That's one thing that concerns me about Tuttle."). A clue of what? What about his transfer status concerns you, and what are you concerned about?
My point was that transferring is a common occurrence these days and is not, in and of itself, any cause for concern. Just like recruits out of high school, some transfers work out for the new school and others don't. Reasons for transferring run the gamut from a revised downward evaluation of the player by the coaching staff, to a personality clash with the coaching staff, to roster changes, to a failure to get the coveted "starter" guarantee the player seeks, to simply a need for a fresh start. But the bottom line, particularly with QBs, is that it's now a revolving door and transferring is the new normal - - see, for example, Kelly Bryant, Hunter Johnson, Justin Fields, Matthew Baldwin, Tate Martell, Tommy Stevens, etc. A transfer, by itself, doesn't raise red flags anymore, except perhaps with you.
