One of the benefits of a rookie minicamp, like the one the Bengals are undergoing this weekend, is that it gives the coaching staff a handle on what their prospects can do and where they'll fit within the team's plans. I know what you're thinking. They don't know already?

It's one thing to scout and interview players, but quite another to get those players on the field, running your own plays and where that player integrates into the team's overall philosophy. If any of you work as managers looking to fill vacancies underneath you, you'll probably understand the difference between a "prospect" and someone hired to fill that position as much as anyone.

Bengals offensive coordinator Jay Gruden is trying to figure that out with third-round rookie wide receiver Mohamed Sanu, according to Paul Dehner Jr. with CBSsports.com's Rapid Reports.

"We're trying to give him as much as he can handle from outside-inside, see what he is good at and what he is comfortable with."

The Bengals are in need for someone to step up as the team's No. 2 receiver. And it appears to be fairly open between rookies Sanu and Marvin Lewis Jones, as well as first-year players Armon Binns and Vidal Hazelton.
