When quarterback coach George Whitfield Jr. said earlier this week NFL teams have been shadowing and spying on quarterback prospect Jamies Winston, who could be the top pick in the 2015 NFL Draft, it was obviously met with some doubt.

However, during a radio interview with ESPN on Wednesday, former NFL general manager Mark Dominik gave credence to Whitfield's comments. Dominik said he had a scout shadow Jaguars wide receiver Justin Blackmon leading up to the 2012 NFL Draft since there were concerns about Blackmon's character. Blackmon had a DUI arrest in 2010 and several other minor incidents.

"We found out there was a bar called the Cricket Inn or the Cricket, which was a popular bar there in Oklahoma State," said Dominik, who is now an ESPN analyst. "He [the scout] sat there for one week, went in at 3 o’clock every day and stayed until 11 o’clock at night. That was his job, and we checked how many times did Justin Blackmon come in? And he came in too many times and we took him off our board."

The Bucs had the No. 5 pick in the 2012 draft, which they traded to Jacksonville, who drafted Blackmon. The Bucs acquired the Jaguars' first-round pick and took Mark Barron with the seventh overall pick. The Bucs have the first overall pick in this year's draft.

Since being drafted, Blackmon has appeared in only 20 NFL games. He has three alcohol-related or marijuana-related arrests since turning pro and has been suspended twice by the NFL for violating the league’s substance-abuse policy. He was suspended for the first four games of the 2013 season and then suspended indefinitely on Nov. 1, 2013 for his third failed drug test.
