Making sense of Jets QBs' poor practices

Wednesday's practice was another dud for the top two quarterbacks of the New York Jets.

Starting quarterback Mark Sanchez was an abysmal 7-of-19 with an interception. Backup Tim Tebow wasn't much better. He went 2-of-4 with an interception, according to my colleague, Rich Cimini of ESPNNewYork.com.

Is it time to be concerned?

It is less than a week into training camp, and both Sanchez and Tebow have put together several poor practices. The Jets were hoping for consistency at the start of camp.

There is already a sense of angst among Jet fans. Sanchez took a step back last year with poor decision-making, too many turnovers and a lack of accuracy. He is entering his fourth season on the shortest leash of his career.

Tebow continues to be one of the most polarizing athletes in sports. His throwing motion and accuracy need a lot of work, but Tebow has proven he can win games. But both quarterbacks struggling in practice doesn't help the team gain confidence in the position.

To be fair, both Sanchez and Tebow are practicing against one of the best defenses in the NFL. Throwing every day against cornerbacks Darrelle Revis and Antonio Cromartie would be a challenge for any quarterback.

But Sanchez and Tebow must compete and prove they are up for the task. So far, they have come up short.
