OH I definitely see Rhule using Sims this year in different situations in games that call for it. But not as a QB controversy. Inside the 10 and short yardage around midfield for sure. Because Sims can sling it, and not limited to QB draws or under center to plow for short yard conversions (guarantee we will see QB pushes happening a lot in those situations).
I'm cool with whoever wins the QB job. But I also think both will see the field. I believe it's Casey's job, and Sims will have to beat out the returning starter. If you don't think so, then ask yourself if new guys and backups are going to beat out returning starters like Corcoran & Benhart as well.
