Consider the circumstances- the new enforcement of "Thr Rule." Shutdown corners around the league have had an off-year this season, arguably because of this rule. The League probably won't do much of anything to change it, and with Rolle being a more physical type of corner, I don't see him being any different from this season's C-mac, Bailey, etc.
Haven't seen either of them play much so that's just off a hunch....
