Allen: No on-field concerns for Manziel

Oakland Raiders coach Dennis Allen should have a unique perspective on Texas A&M quarterback Johnny Manziel as Allen also played football for the Aggies.

Though Manziel had an impressive Pro Day in College Station on Thursday, Allen acknowledged there is more than on-field play to evaluate when it comes to the Heisman Trophy-winning artist known as Johnny Football.

Especially with the Raiders holding the No. 5 overall draft pick and having just acquired veteran quarterback Matt Schaub in a trade with the Houston Texans for a sixth-round draft pick.

“The biggest thing you have to look at with Johnny, it’s really not as much what you see on the field, but all the other things surrounding him -- the media attention, the ‘celebrity’ of Johnny Manziel,” Allen told the Houston Chronicle. “Those are all things, as he continues to mature, that he’ll be able to handle. And if he’s able to handle those things and keep them under control, he’s going to have a successful career.”

Allen also said the relatively small Manziel has “well above average” arm strength.

The media circus -- former President George Bush was in the house -- that attended the Pro Day also got a chance to see receiver Mike Evans, who could vault into the top 10 of the draft.

It gave teams a chance to see just how much attention Manziel will bring with him to the NFL. ESPN NFL Nation Houston Texans reporter Tania Ganguli reported that 75 representatives from teams were at the workout, including eight general managers and eight head coaches. Though Allen, offensive coordinator Greg Olson and QB coach John DeFilippo were there, Oakland GM Reggie McKenzie was not.
