Here we go again.

Jets coach Rex Ryan left open the possibility the team could use a two quarterback system this fall with Mark Sanchez and Geno Smith just months after scrapping the failed Tim Tebow experiment.

Ryan answered a question about using Smith in a role similar to what the 49ers did with Colin Kaepernick early last season before he became the starter, and said yes the Jets could do something similar with Smith if he doesn’t win the starting job.

“I know what everybody’s thinking if we did that — didn’t we try that last year?” Ryan said, taking a playful jab at himself over the Tebow situation. “I think certainly that’s a possibility. To probably make assumptions now probably isn’t the thing to do, but we’ll let this thing work out and pan out and we’ll see.”

The Jets saw Kaepernick’s ability first-hand in Week 4 last season when he ran for 50 yards and a touchdown, subbing for Alex Smith, in a 34-0 San Francisco win.

The difference between Kaepernick and Smith, though, is Kaepernick ran a pistol offense in college that was similar to the read-option offense the 49ers used last year with him. Smith ran some read-option plays early in his college career at West Virginia but not in the system the Mountaineers ran the last two years.

According to ESPN, Smith attempted just 11 designed runs in 2012 and averaged 2.6 yards on those carries. He did scramble for 253 yards. Despite this, Ryan said he believes Smith can be effective in the read-option, which has become the latest fad in the NFL.
