Bengals QB coach Ken Zampese attended Garrett Grayson pro day

Cincinnati Bengals quarterbacks coach Ken Zampese attended the pro day of Colorado State quarterback Garrett Grayson on Monday. Colorado State originally had their pro day on March 10, but Grayson pushed back his pro day to March 23, allowing time for his hamstring to recover -- which he injured in preparation for the NFL scouting combine last month forcing him to not participate.

Grayson is viewed among the "next tier" of quarterbacks heading into the NFL draft, behind obvious first-round projections like Florida State's Jameis Winston and Oregon's Marcus Mariota, but among names like Baylor's Bryce Petty and UCLA's Brett Hundley.

Cincinnati isn't exactly in the market for a first-tier passer but the possibility of drafting another young quarterback isn't outside the realm of possibility. The Bengals appear to be growing comfortable with promoting AJ McCarron as the team's primary backup behind Andy Dalton, but haven't ruled out the idea of drafting a young quarterback as a third-stringer -- which Grayson probably isn't.

Also in attendance were scouts from the Buffalo Bills, Green Bay Packers, Cleveland Browns, Denver Broncos, Detroit Lions, Miami Dolphins, Minnesota Vikings, New York Jets, Oakland Raiders and St. Louis Rams.
