If I remember right, Moses was #1 in NFL Europe, and also had numbers last year similar to Dante's first year. I'm looking forward to the competition, but wonder if Moses will continue to develop? Dante's numbers went up after his first year, it makes sense Moses' might also.
Related to whether Moses or Duff should stay if they were equal at returns, I'd say this. My son used to play corner back and wide receiver. It's a lot more damaging to a team when a CB blows it than when a WR blows it.
