SAN DIEGO -- Johnny Manziel has to show that he is a changed man.
Scouts from 13 NFL teams were on hand to watch Manziel throw. The Browns,New England Patriots, Chicago Bears,Los Angeles Chargers, New York Giants, Kansas City Chiefs, New York Jets, Oakland Raiders, Tennessee Titans, Detroit Lions, Jacksonville Jaguars, Carolina Panthers and Tampa Bay Buccaneers were represented.
Manziel, 25, showed the arm strength and athleticism that helped him become the first freshman to win the Heisman Trophy. The former Texas A&M star attempted 38 passes, with two misses, in light rain.
"It was good," Dwelley said. "He spins a good ball. He saw it as a good opportunity to get his foot back in the door, so he was all over it. So it was a good opportunity for both parties."
Manziel said he has been working with quarterbacks coach George Whitfield in San Diego for the past three weeks, and they will work for another week before Manziel reports to Austin, Texas, for the Spring League, a developmental football league.
"What an opportunity," Whitfield said. "The last time he threw the football in an official capacity for the NFL, he was wearing a Cleveland Browns uniform. So he's a completely different young man at a completely different stage in his life.
"I'm sure there's a lot of questions -- rightfully so -- about him. Where he is, what is his level of dedication -- and can he even throw the ball? Do you even play, bro?" Whitfield said, laughing. "So he's been working and training."
Manziel, a former first-round pick, was released by the Browns after two seasons; alcohol and substance abuse helped to lead to his demise.
He said Thursday that he's in a much better place mentally, and he believes he has not reached his athletic peak.
"I drive down here [to San Diego] a couple times a week and [I] work out six days a week, and that's pretty much the schedule," said Manziel, who lives in Los Angeles with his wife, Bre. "I'm a married man. I'm at home with my wife and my dogs, and I don't have a lot of time after that after doing six-hour training days.
"I'm happy with where things are. I think things are going well, and I couldn't ask for a better place to be in my life right now."
Selected No. 22 overall in the 2014 by the Browns, Manziel played in just 14 games over two seasons, completing 57 percent of his passes for 1,675 yards, 7 touchdowns and 7 interceptions. He also ran for259 yards and 1 score.

Manziel said his hope is that after proving he can stay sober and continue to put in solid work in the weight room, NFL decision-makers will trust that he's mature enough to handle the responsibility and stress of being a quarterback in the league.
"I know I've rubbed people the wrong way," Manziel said. "I know there's still people that still doubt what I'm doing and still doubt where I'm at.
"For me, [I have] spurts in the past of being good. I've spurts in the past of showing promise and looking like I'm on the right path, and when I think I get there, something else happens. That's kind of the pattern that's been there in the last couple years of my life since college. So for me, the key right now is to be consistent and to continue what I'm doing day in and day out."
