Aqib Talib is a player that has gotten better since he came to the Denver Broncos in 2014. In 2017, he was one of the least targeted cornerbacks in the NFL and for good reason. He spearheaded a secondary that helped the Broncos to fourth overall in yards per game, despite the No Fly Zone widely being seen as no longer dominant.
While that might be the case, the No Fly Zone was still dangerous and dangerous means they are still a good unit.
According to Pro Footbll Focus, Talib was an elite cornerback by every measure they could come up with.
