Athletic QBs that can pass and also rush, run routes, and catch. Multiple formations and sets with 2 or even 3 hybrid QBs on the field at the same time. QB starts in shotgun, then motions out to the slot, while the split receiver (hybrid QB) motions into the QB position. Lots of RPO alternatives and even option-pass, jet-sweep-pass, reverse-pass, and screen-pass-pass plays.
It would be innovative to have 2 or 3 guys each have 10+ pass attempts in addition to multiple rushes and pass targets...in the same game. The first 10pass-10rush-10catch stat line would be amazing!
