Texas A&M Aggies quarterback Johnny Manziel has insisted that he will not abandon his running game when he is drafted into the NFL this year.

Manziel is widely regarded as one of the top prospects in May's Draft, having forged a successful college career that saw him win the Heisman Trophy in 2012.

"The game's evolving. More and more [pass-rushers] like [Jadeveon] Clowney are coming out of college, and they're big and they can run. You have to be able to create plays," Manziel told the Houston Chronicle.

"I want to be a pocket passer too and be able to pick apart defenses and beat teams with my arm. But when a play breaks down, the scrambling and running ability [take over], and we're back to doing what I've been doing the past six years playing football."

Manziel has been tipped to remain in Texas following the Draft, with the Houston Texans having the first pick.
