FLORHAM PARK, N.J. -- Mark Sanchez and Tim Tebow received effusive praise from their coaches, but both quarterbacks were uneven Tuesday on the field as the Jets opened a three-day minicamp.

Working with a patchwork receiving corps, Sanchez and Tebow struggled to find open receivers, sometimes resulting in "sacks" and hurried throws. It wasn't pretty, but, remember, they're learning a new offense. The good news: no turnovers.

The unofficial stats from the non-contact practice:

TEAM DRILLS

Sanchez: 2-for-9, three sacks, two near-interceptions. He was almost picked off by CB Darrelle Revis and rookie DE Quinton Coples, who let a pass bounce off his hands. It was a poor throw, shades of the season finale in Miami, where Sanchez was picked off twice by DL Randy Starks on check downs.

Tebow: 5-for-9, one sack, one TD pass. Tebow, working exclusively with the second-team offense, made a nice completion to WR Jeremy Kerley on a deep cross. His TD was an easy toss to a wide-open TE Dustin Keller.

SEVEN-ON-SEVEN DRILLS

Sanchez: 6-for-11, three TDs. His best throw came in the red zone, when he rifled a pass to Keller in the back of the end zone. Later, OC Tony Sparano called it a picture-perfect play -- right read, excellent throw.

Tebow: 1-for-4. Tebow missed a wide-open Kerley on a seam route that would've resulted in a touchdown. He underthrew Kerley and it was nearly picked off.

TWO-MINUTE DRILL

Sanchez: He took over at the opponents' 25 with 45 seconds on the clock, trailing by four points. A first-down sack pushed him back, but he hit Keller for 26 yards on a well-thrown post. With four seconds left, ball on the 5, Sanchez hit Kerley on a short pass ... and he was stopped by Revis at the 1. If this happened in a real game, they never would've heard the end of it.

Tebow: Placed in the same situation as Sanchez, Tebow did worse, taking a sack from the 18 as time expired.

Afterward, Sparano praised Sanchez's overall performance in the offseason, noting his ability to make all throws. Sparano said Tebow is showing daily improvement with his throwing mechanics, always an issue for him.

"Every day I see a ball come off his hand that's better than it was yesterday or the last time we practiced," Sparano said.
