Johnny Manziel performed well at his pro day -- so well, in fact, that some of his loudest critics have started to support the increasingly famous quarterback.

"In studying the game tape of Johnny Manziel, I saw flaws in his mechanics," ESPN's Ron Jaworski said on the network. "George Whitfield has done a terrific job of coaching him up. I did not see those flaws in mechanics [at his pro day]. I saw him stand on his back foot, driving the football. Throwing the football with velocity and accuracy."

The drastic change in opinion is reminiscient of the way people thought about Tim Tebow, another player who was very popular as he left college but had many critics who doubted his ability to perform in the NFL. For what it is worth, Tebow is now out of the league.

"This is one piece of the puzzle we put together, but I saw a tremendous improvement in the mechanics of Johnny Manziel," Jaworski added. "I loved the fact that he put the helmet on, he put the pads on, and he had the rib protector on. All those things that will affect a quarterback on a Sunday. So yes -- he moves up on my board."

Another topic of discussion has to do with Manziel and coaching. Some are wondering whether or not the Heisman trophy winner is willing to make adjustments at the professional level in order to optimize his potential in the future.

When do you think Manziel will be taken in the NFL Draft? Do you expect him to be the top pick or do you think he might end up slipping on the board come draft day? Which team do you think he would fit best on? Let us know what you think in the comments section located down below.
