3. Evan Hull
For a player like Evan Hull, this is exactly the opportunity that he would be looking for entering his rookie season out of Northwestern. He put up 1,459 total scrimmage yards in his senior season and has shown he can make an impact in both the rushing and passing games.
His explosiveness may not be there as much as Taylor, but he is a smart runner and pass catcher, and makes smart decisions to know when to use his skill set. While he has to develop more as a blocker, letting him play more on screen plays and check-downs could allow him to make an early impact, especially with a rookie quarterback who will look to go to his check-downs and take fewer risks.
What Hull will need to do is take advantage of the opportunities he receives on the field, Moss and Jackson will most likely be getting more snaps due to experience and pass-blocking abilities, but for the rookie, a few big plays when his name gets called could put some eyes on him as these four games go along.
He had a solid game against Philadelphia in preseason play with six carries, 25 yards, and a touchdown that let Colts fans know he is here and here to play. In that final preseason game, he looked much more comfortable in this offense as well, it will just be up to him to make the most of what is given to him during Taylor's absence.
