Fewer receptions, fewer yards, fewer touchdowns, more turnovers.
He virtually disappeared over the last seven regular-season games, catching 16 passes for 175 yards and no touchdowns. He lost a fumble.
Then came Saturday's playoff game and -- whammo! -- Keller reminded everyone why the Jets used a late first-round draft choice on him. They thought Keller could become a weapon, a pass-catching mismatch to open up the offense.
Keller caught three passes for 99 yards and a touchdown in the first-round postseason victory over the Cincinnati Bengals. He also made the critical block to clear a path for Shonn Greene's 39-yard touchdown run.
Now that's an X-factor: a player capable of materializing almost out of nowhere and providing substantial contributions to victory.
"Here's a guy where everybody realizes what his strengths are: speed and the ability to catch the football," Jets offensive coordinator Brian Schottenheimer said. "He's a matchup problem for defenses."
Keller erupted a couple of times during the season. On opening day, he had four receptions for 94 yards to help the Jets beat the Houston Texans. In Week 8 against the Miami Dolphins, he had eight catches for 76 yards and a touchdown.
"He is a dangerous player," Jets head coach Rex Ryan said. "If you want to cover him with one guy, then surely we can exploit that. We have a lot of confidence in him. He’s a very dangerous type of athlete."
