Right now... Harris is the front runner for #3. Which isn't ideal. Tiny slot options tend to disappear when you give them terrible sideline routes*cough Payton* with no inside leverage over 6ft DBs.
Source? I think Calloway is the next in line....for Harty to be they would pretty much have to take him off special teams duty....I don't expect them to do that but we will see....Maybe they think Easop is ready to replace him (which I'm actually hoping for) but Harty is one of the best, if not the best returner in the NFL.....
I think Harty will be a contributor but they will use him more sparingly than Calloway.....
