He got all the attention. All the throws. But rookie camp is over and the veterans come back for team organized workouts the next three weeks.

Now Chang, alone, has to face the long road ahead.

Is he worthy?

"It's hard to say," Kruczek said. "The next step is on Timmy — his retention on how much work he puts in during the summer, studying (the offense), then take that work that he did in June into training camp and when he gets into preseason games. And take advantage of the opportunities given in those games."

The fact that Kruczek mentioned the words "Timmy" and "preseason games" in the same breath bodes well for Chang. That would mean he would make it past training camp in August and still be on the roster in September.

Kruczek said he's been pleased with Chang's progress. But it's safe to say Chang won't crack the team's top three quarterback positions held by starter Kurt Warner, backup Josh McCown and John Navarre.

Kruczek said he "would imagine" that Chang is battling for a practice squad spot with Chris Lewis, who is a backup in NFL Europe.

Chang knows what he has to do. Watch. Study. Learn. Repeat.

"Those are the intangibles that I must do in order to succeed," said Chang, who is renting an apartment and flies back to Hawai'i every weekend on his own money. "I was very fortunate to be the only quarterback (in rookie camp), getting all the reps. Now that we have the other three guys coming in, for me, it's more sit back and watch what they do and learn from their experiences, take those visual reps and keep processing it and when I go home later, just keep learning the playbook."

Kruczek said Chang, who earns $400 a week during the team's 14-week offseason workout program, "drastically improved" at taking snaps from under center and working on his footwork, which were Chang's worst quarterback skills.

But the rookie, no doubt, is a quarterback. Now it's up to him to become one in the NFL.

"He's very rhythmical, which means he doesn't hold the football," Kruczek said. "When he hits his back foot, he threw the ball down the field. He's a timing guy, which is nice to see.
