With the 21st pick in the 2012 draft, the Bengals select...
WR-Michael Floyd-Notre Dame
While the Bengals did draft a WR and a QB last year, their defense was a top ten defense last year. Their offense was in the bottom half. WR is not a huge need, but the Bengals don't have a huge need after a busy Free Agency.
They were in no way expected by anyone to draft a WR, but when a guy like this falls this far it is not a bad idea to take him. They already drafted Dre Kirkpatrick, and this pick gives them a strong first round. Dalton-Green-Floyd are a regular team on highlight films for the next 5 years.
And just for a little extra analysis, his arrest record seemed to really fit the direction they decided on many years ago.
