A lot of football experts, who do this football thing for a living (and have for decades), are very high on Allen's potential as an NFL QB. If the staff is confident that he can be a franchise QB, I'm more than okay with trading up into the Top5 to land him.
Sure, in a perfect world I'd rather wait until 12 or make a slight trade and still get him, but if he's your franchise QB, go get him.
