Of course you are correct, we haven't seen enough. None of us knows for sure what coaches think or have planned. But, what I am suggesting is that Kramer's wildcat package is being expanded to see more passing from different parts of the field and different situations.
Green came in for short yardage power runs, usually near the goal line. It worked because Seth had size and power.
Kramer is different. He is an actual QB who is also an excellent runner. They can bring him in anywhere on the field and leave him there to run an entire series of downs.
And I just wonder if there is a situation, say in the 4th quarter of a tight game, where Tanner is hurt that you wouldn't go with the guy who has already run ten or so snaps in the game and has been playing every game since very early in the year, rather than bringing in a guy who has not had meaningful game experience since 2018.
Without knowing anything about the inside planning I am just guessing Kramer would be our No. 2 in that situation.
