As seen in the following video, Manziel was vocal about college athletes being compensated:
"It's time," Manziel said. "I doubt it'll get done, but we'll see."
With regard to Barkley, Manziel called him a "beast" and said he's "pulling for him" when it comes to potentially being the No. 1 overall pick in the 2018 NFL draft.
On Wednesday, Manziel responded to a Bleacher Report tweet about the NCAA making $1.1 billion in revenue during the 2017 fiscal year.
One of Manziel's tweets read "PAY UP PAY UP," and the other mentioned his desire to be paid for money the NCAA made off him during his collegiate playing days:
Pay-for-play has been a hot-button issue as of late in the wake of a report from Yahoo Sports' Pat Forde and Pete Thamel in which numerous programs and players were named in relation to an FBI probe surrounding corruption in college basketball.
Also, Manziel recently posted a photo of himself with Barkley on Instagram following an apparent workout:
Johnny Football called Barkley the "undisputed" top pick in the draft.
Barkley put forth a dominant performance at the NFL Scouting Combine, and in his most recent mock draft, Bleacher Report's Matt Miller predicted that Manziel's former team, the Cleveland Browns, will take Barkley No. 1 overall.
