During ESPN's SportsCenter special (aka pre-draft show), Bob Holtzman reported that the Cincinnati Bengals have Georgia wide receiver A.J. Green on top of their draft board. This isn't too terribly surprising, considering that Green is the odds on favorite to become this year's fourth overall selection. If Green is selected before the Bengals, then the board falls to a "handful of defensive players."
Holtzman pointed out though that the Bengals are working the phones to drop down in the first round, making a trade "if the deal is right". We largely assume the "deal" would benefit the Bengals in selecting TCU quarterback Andy Dalton.
But if no trade happens by the time Cincinnati is forced to make a selection and A.J. Green is still available, then expect the Bengals to draft Green fourth overall.
