Coaches have always tried to implement the R-O it in some shape or form.Randall Cunningham-Kordell "slash" Stewart-Michael Vick. Now Wilson-RGIII-Colin Kaepernick. Wildcat is pretty much a gadget play.Miami had the right personel at the right time to use it longer than any pro team would dare.
This year and next defensive Co-ordinators will slow down the R O down. It wont be reduced to the wildcat but it will be slowed down by the methods above.Teams must make the decision on how much they want to risk their QB,the most important position on the team.
Jets grabbed Geno Smith I'm guessing to implement the butt fumble read-option.
