I'm not saying get rid of it completely. But there are numerous times Luck has an underneath player open and chooses the deep play
I was a STH and seeing Dorsett open on a slant or crossing route get open and Luck pass on that read was very frustrating.
The main adjustment I believe that has needed to be made is not so many 7 step drops because the Oline isn't good enough yet. Once it's solid and can sustain. then by all means stretch the field
and of course TY is going to say that. He's a receiver. He wants big yards
