WR B signs a 6-year, $32 million deal with $9.5 million in guarantees. In his best season he has 77 receptions for 1110 yards and 6 TDs.
WR C signs a 5 year deal, $27 million deal(not entirely sure about the guaranteed money). In his best season he has 46 receptions for 816 yards 8 TDs.
WR A is Bernard Berrian, who was signed by the Vikings yesterday. WR B is Kevin Curtis. WR C is Reggie Brown.
Now, it's fair to say that Kevin Curtis' best year came after he signed the deal, but it is the first year he was a starter all year. Even before that though, Curtis' best year of 60 rec for 801 yds and 6 TDs holds up very well against Berrian's best.
