Heck Jerry Rice became the best receiver to ever play running 3 routes, an out, a slant and a post. Randy Moss made a living with the go pattern and jump ball. I'm no way comparing MT but I don't have a problem with his perfecting just a couple routes in the Payton system. He was the best at his position for one year. Its too bad the rest of his career after that season was marred by injuries, and now by his social media posts.
