Drafted at No. 153 overall, Richardson's contract will closely reflect that of 2013's No. 153 overall pick, Atlanta defensive end Stansly Maponga, who signed a four-year, $2.35 million contract with a $186,740 signing bonus last May.
One of the more decorated offensive linemen in college football in his career at Baylor, the 6'5", 329-pound guard fell in the draft thanks to a poor showing at the Senior Bowl in January. Though he played left guard (as well as left tackle for a year) in college, Richardson spent the team's rookie minicamp working at right guard.
Richardson is the fifth of Buffalo's seven draft picks to sign their rookie deals, joining third-round linebacker Preston Brown, fourth-round cornerback Ross Cockrell, seventh-round linebacker Randell Johnson, and seventh-round tackle Seantrel Henderson. That leaves just two rookies left to sign: No. 4 overall pick Sammy Watkins, and the likely new starting right tackle, Cyrus Kouandjio.
