What Key People Say About Manziel

In an exclusive interview with NFL Network, left tackle Joe Thomas said that Manziel's difference in attitude has already been noted by his Browns teammates.

"The way he is now is night and day from last year," Thomas said.

Aside from Thomas, more people are noticing the "new" Manziel. Offensive coordinator John DeFilippo had nothing but praises for Manziel during the recent rookie camp. 

"Johnny's been great. He's been fantastic. All I know is Johnny the football player, and he's been awesome. He's been working hard, very hard with myself and (quarterbacks coach Kevin O'Connell), and doing what we want him to do on the field," DeFilippo said.

The coordinator specificaly noted the player's attitude as a professional football player.  

"He's been nothing but a consummate professional," DeFilippo added. "He's spent every hour that he's been allowed to spend in this building. We give them worksheets every Tuesday and every Friday, and they're done to the unbelievable detail that we need an NFL quarterback to do."

Manziel's better behavior were also noticed by teammate Joe Haden, who was elated of the marked improvement from Manziel, reports Sporting News. But more than the approval of his improved work ethic, Browns general manager Ray Farmer said the former Texas A&M standout must live up to expectations next season.

"This is still the National Football League. There's no rest for the weary. We get it. We're supportive of him and his personal endeavors and he's got to come out and perform and demonstrate that he's worthy of being on the 53-man roster,'' Farmer said in the camp.
