The Bengals have signed Purdue cornerback, Frankie Williams as an undrafted free agent according to Williams.
Williams has experience with punt returning and due to his small size, 5'9", 186 pounds, there's some talk that he could switch to safety.
Here's an excerpt from his Draft profile on Hammer and Rails, SB Nation's Purdue website.
Williams had an excellent career for a very bad team. That is the best way to sum up his time in West Lafayette. He started as a redshirt freshman for Danny Hope in 2012 and played in almost every game in his career. In 2014 he was a second team all-Big Ten selection and had a total of 74 tackles and three interceptions. One of those picks was a long return for a touchdown against Iowa. As a senior he was an honorable mention all-Big Ten selection with 47 tackles and three more picks as teams played away from him. He served as Purdue's primary punt returner and averaged eight yards per return.
At CBSSports.com, Dane Brugler ranked Williams as the 51st best cornerback in this year's Draft class.
Williams is quicker than fast with a smooth pedal, swivel hips and flexible joints to easily change directions and react to throws. Plays bigger than he looks in the run game, aggressively striking through his target and finishing strong.
