I think Taysom has always taken the chance to run as soon as he sees it, but Ty is telling him. Let the play develop and then after options 4, 5, and 6, go do what you can. This is what made Ty so great. He wasn't physically gifted like Taysom, but he was wise.
Not worth risking his health on the first two downs and or in games we are in control.

Health first!
