Exactly, it is the speed difference in the NFL that will limit his coverage ability. You play to player's strengths and adjust. Dansby allowed Bowles more flexibility but really he could not cover a TE either all that well... look at what TEs did to us lol
So who was Dansby covering to get 19 pass deflections? 16 more than Paris Lenon in '12. Of course our opponents had 625 pass attempts in 2013 compared to 497 the year before.
