Putting past season woes and personal issues behind him, former TCU quarterback Casey Pachall hopes to show the NFL something different — a new Casey Pachall that is leaner, faster and ready to play professional football.

“Everybody has made mistakes, and he’s getting a great chance and a great second chance to come back and show people who he really is,” Brian Abadie said.

Abadie, the director of elite performance at Michael Johnson Performance, has been working with Pachall since December.

Since checking into the Michael Johnson Performance program, Pachall has been eating a new diet of primarily carbohydrates, polishing his throwing technique and working on improving his agility.

“He’s more explosive,” Abadie said, “I think some of the doubts from the athleticism side, I think he’ll prove some people wrong.”

One element Pachall has been focusing on is reshaping his physique. The 6-foot-5, 230 pound Brownwood, Texas, native has been working with nutritional physiologist Krista Austin to develop more muscle mass.

“We wanted to stay at the weight he was at and to lean up a bit,” Austin said. “That means we just needed to convert the fat mass he had to muscle mass.”

Austin said Pachall has to eat a minimum of 3,000 calories a day but the calorie amount varies depending on the intensity of Pachall’s training for the day. His diet consists of primarily low glycemic carbohydrates, along with lean proteins and healthy fats.

Abadie said Pachall has become significantly faster since changing his diet.

And Pachall’s athleticism isn’t the only thing he’s working on either.

To improve his quarterback technique, Pachall is training with Old School Quarterbacks CEO Brad Frazier. Old School Quarterbacks has been teaching leadership and critical thinking skills since 2003, according to their mission statement.

Frazier said Pachall is working to be more automatic with his movement, practicing drop mechanics and gaining confidence outside the pocket.

“He thrives in a position where it’s fourth and one,” Frazier said. “He wants the ball. He’s a gamer.”

And although Frazier doesn’t think Pachall will be a starting quarterback in the NFL, he does think that Pachall’s intuition and knowledge of the game will get him drafted by a team come May.

Abadie agrees.

“Is he gonna be a top athlete in the NFL? No,” Abadie said. “But does he have the athleticism to play in the NFL? Absolutely.”

After closing the 2013 season with a 4-8 record and 10 interceptions, Pachall is still trying to clean up the memories of the 2013 season. Not to mention his controversial DWI arrest in 2012.

“Some of the snafus and things that he’s had in college is, I think, are things that he’s cleaned up,” Abadie said.

Abadie added that Pachall is “a very coachable young man” and that his experience has only made him a better football player.

Pachall ended his career as TCU’s all-time leader in completion percentage. He threw for 42 touchdowns and over 5000 yards in 32 games played.

“I think he’s gonna be a big-time steal for whoever drafts him,” Abadie said.

Despite not being invited to last week’s NFL Combine, Pachall will have a chance to impress scouts on Thursday at TCU’s Pro Day.

Pachall declined an interview with TCU 360.
