Texas A&M quarterback Johnny Manziel declared himself ready for the NFL, in his estimation, but said Wednesday he will seek advice from others before making himself available as an underclassman in the 2014 NFL Draft. But the 2012 Heisman Trophy winner left no doubt that he considers his skill set sufficient to begin a professional career next season. “In my mind, I think I am,” Manziel said in his strongest hint to date about his post-bowl intentions. “I feel like I’m playing, for the most part, at a really high level of football. I’m putting the ball where I want it to be and I’m throwing it with a lot of velocity.” Manziel, a third-year sophomore, improved his completion percentage (69.1) and his number of touchdown passes (33) from his Heisman-winning season while leading No. 21 A&M (8-4) to a berth in the Chick-fil-A Bowl against No. 24 Duke (10-3). A finalist for the 2013 Davey O’Brien National Quarterback Award, which will be presented Thursday night at the Home Depot College Football Awards show (6 p.m., ESPN), Manziel ranked among the nation’s top nine players in passing yards (3,732), total offense (4,418 yards) and passing efficiency (170.4 rating). But he will use “the next couple of weeks,” Manziel said, to huddle with A&M coach Kevin Sumlin, private passing instructor George Whitfield Jr. and others before making his call about calling it a career at A&M. He did acknowledge he already has begun thinking about his A&M legacy.
