The Cincinnati Bengals have signed a number of college free agents since the conclusion of the 2015 NFL draft. They've yet to release their official list (it'll come out soon enough), but there are a handful of players who we know about.
Chris Jasperse, C, Cincinnati Bengals
The Bengals have a habit of finding good lineman. Whether drafted or not, Jasperse has some potential to latch on long-term on the inside after man handling the competition for Marshall. There is one alarming concern with him and that’s his ridiculous tendency to draw penalty flags (13 of them last year and mostly false starts) but even with those issues he still had the second-highest grade of all draft eligible centers. Didn’t let himself down in the Senior Bowl at all.
Troy Hill, CB, Oregon, Cincinnati Bengals
With the way this cornerback class was bunched together, both myself and Sam Monson actually saw Hill as one of the five best available. Our sixth-highest graded player at the position, Hill allowed just 435 yards and a quarterback rating of 63.9 on passes thrown into his coverage. His 11 pass breakups were tied for second in the class, and he added an interception for good measure.
