As he gets ready for the NFL draft, Johnny Manziel has again taken to Instagram to show off his dunking abilities.

This time the former Heisman Trophy winner put on a show with a number of alley-oop slams.

Update: Wednesday, March 26 at 6:40 p.m. ET

In response to claims that he wasn't dunking on a 10-foot hoop, Manziel posted a slow-motion video to his Instagram with the caption:

"Shout out to @mikeevans13_ for the slow motion. Let me guess..y'all think this rim isn't 10ft either"

Manziel previously showed off his dunking skills in February with former Texas A&M teammate Mike Evans.

The potential first-round pick recorded a 31.5-inch vertical jump at the NFL combine, ranking fifth among quarterbacks.
