Now, it is possible the interpretation was “I wanted to move him but since he was doing well on the second unit I decided not to move him” as opposed to “ he asked to stay on the second unit” but when Kelly Moore re-played it he said Ehlers made the request to stay on 2 as the QB.
Not in the clip but also in that presser, PoMo ended the session after questions about the vets and how the rookies looked with “well you all know it doesn’t matter because I love the vets and refuse to give the round guys a shot, right? Isn’t that the story with me?” Throwing major shade at the armchair GMs on Twitter, it was hilarious and beautiful.Media all got a big laugh out of it.
