"I think about it as, what a blessing," Tebow said after Thursday's practice. "What a great opportunity. I work extremely hard every day, try to be the best teammate I can, the best player. Try to make everybody else around me better as well. All of us are just trying to improve."
QB Sam Bradford, the other Heisman winner acquired by Eagles coach Chip Kelly this offseason, has not been cleared to take part in team drills. Bradford tore his left anterior cruciate ligament last August. He can take part in limited drills, but not in many of the practice periods.
For Tebow, this opportunity came after two seasons of being out of the league. He did some college football analysis for ESPN last season. He has appeared on "Good Morning America." But the whole time, Tebow was working with throwing coach Tom House to try to improve his mechanics and get another chance in the NFL.
"I still competed," Tebow said. "I trained every single day. You should have seen the Tebow Turkey Bowl. That was the craziest thing ever. You try to compete at everything you do. I'm a competitive person.
"Whether that's training every day, whether it's going to play hoops, throwing a ball, whether it's what I was doing on TV with ESPN and GMA and everything, I enjoyed that and competed at it. You always want to do your best. Whatever you find to do, do it with all your might. That's something I believe in."
Now that he is back on the field, Tebow has a new appreciation for the game.
"All I know is that I'm enjoying this process," Tebow said. "I'm going to take it day by day and try to get better. And also enjoy the opportunities. I think sometimes when things get taken away, you don't realize how much fun it is to come out here and play this game. You can't play it forever. I'm going to enjoy it."
He has a chance with the Eagles. Kelly has seemed lukewarm about Barkley, choosing not to let the third-year quarterback from USC start the Eagles' final regular-season game. Even though the Eagles were officially eliminated from playoff contention, Sanchez started that game against the New York Giants.
Kelly signed Tebow to a one-year contract on April 20, so the coach's interest in Tebow is more apparent. With Bradford sidelined, Tebow will have plenty of practice opportunities to impress Kelly and the other coaches.
"I've always loved it," Tebow said. "I think you appreciate it more now. I appreciate every opportunity that I get, every day of being able to come out here -- no matter how hot it is, no matter how much you've been running, no matter how the workout was. You embrace it. You embrace that grind even more. You find joy in it, especially the hard stuff."
