Richard Sherman, in his four years in the NFL, has become both one of the league's top cornerbacks and one of its most outspoken players.
The Seattle Seahawks star's controversial style means he isn't always the most popular player amongst his peers, with not all of them sharing his belief that he is the top CB out there.
And, after rifts with a number of his positional rivals down the year, New York Jets corner Antonio Cromartie has become the latest to lay into Sherman - stating there is no way he should be considered the best because of one fundamental issue.

Speaking to Sirius XM NFL Radio, Cromartie insisted Richard Sherman would never be considered the very best until he moved away from his left-field only coverage:
"Go play in a defense where you don't have two All-Pro safeties. Go follow the number one receiver," the Jets man began.

"Follow him around for a whole entire game and see what you can do. Darrelle Revis has done it his whole career. I've done it, Patrick Peterson has done it, Joe Haden has done it. He (Sherman) is the only defensive back that hasn't."
Cromartie's willingness to slate the Seahawks star may have something to do with the fact that he has recently linked up once again with the other main contender for the NFL's top cornerback, Darrelle Revis.
His point concerning Sherman's restricted play - whether his decision or one enforced by the Seattle hierarchy - remains valid.
"There's no point in critiquing him. If you want to label yourself as the best corner in the NFL, follow the best guy on every single team."
"His whole thing will be 'we don't have to do that, I have trust in the other corner on the other side.' That's not the point. If you want to consider yourself the best, the best do what the best and they follow around the best."
There is no doubt that Richard Sherman has shown he deserves to be considered alongside the likes of Revis and Peterson with some outstanding play since arriving in the league in 2011.
Indeed, in 2014, there were several games where Sherman's reputation meant teams actively stayed away from the left side of the field so as not to give the Stanford Alumni a chance to make a play.
Regardless, until he is given the freedom to follow around a Dez Bryant or a Calvin Johnson for an entire game there will always be those ready to question Sherman's status in the NFL.
Especially if the Seahawks star himself is so keen to big up his ability as has been the case in the past.
Antonio Cromartie may be making a point of critiquing Richard Sherman but he certainly won't have the same negative thoughts about his fellow cornerback in New York.
With Darrelle Revis having returned to the Jets from rivals the New England Patriots this offseason there is a growing excitement that he and Cromartie can help raise the franchise's defensive game up a whole new level.
