PHILADELPHIA -- Jason Smith is a quick study. After only one meeting and an abbreviated practice, the former Rams first-round pick started at left tackle Thursday night and played the entire first half without any glaring mistakes.

The intial play for Smith, acquired Tuesday in the Wayne Hunter trade, to play 10 plays.

"I thought he held up well considering he had been here for one meeting," Rex Ryan said after the Jets' 28-10 loss to the Eagles. "I was proud to see that young man compete like he did."

Obviously, they scaled back the offense for Smith. The Jets played mostly backups, so it was going to be fairly vanilla anyway. Smith credited OL coach Dave DeGuglielmo, saying, "He basically simplified four weeks of training camp into one day. ... It was a crash course."

Smith faced a rookie, second-round DE Vinny Curry, most of the half. The Jets allowed two sacks in the first half -- one by RT Austin Howard, another when a player came free on a stunt. Smith, projected as a backup at both tackle positions, was pleased with his Jets debut.

"I came out of it with a right mind, and I came out of it healthy," he said. "I enjoyed the time I spent out there with the other guys, learning to play like Jet."
