Indianapolis Colts center Ryan Kelly inked a four-year contract extension Thursday that will pay him $50 million, thereby making him the leagues highest-paid center. Kelly will be integral to the acclimation of quarterback Philip Rivers to the Colts roster in his first season, while also being an anchor of the offensive line for the stylings of running backsMarlon Mack and Jonathan Taylor. While Kelly won’t have any fantasy consideration as a center, his presence up front should help boost a Colts offense that passed for only 194.3 yards per game last season.
