FLORHAM PARK, N.J. — It is easy for a coach to shrug off the possibility of an opponent getting in little to no practice time prior to a game. Especially when he is not staring out the window at 4 feet of snow.

“Well, I downplayed it because we just practiced,” New York Jets coach Rex Ryan said with a laugh Wednesday afternoon.

The Jets worked out in unseasonably cold temperatures Wednesday, which sure beat what the Buffalo Bills did — or didn’t do — 350 miles to the northwest. Players were homebound and coaches were stuck at Ralph Wilson Stadium in suburban Orchard Park, which was among the communities that got hammered with a historic lake-effect snowstorm Monday and Tuesday.

And the storm was not done: Forecasts call for between 1 and 3 more feet of snow Thursday and Friday.

The biblical blizzard is jeopardizing Sunday’s game between the Bills and Jets. Temperatures are supposed to rise into the mid-40s by Sunday, but there may not be enough time — or manpower — to get rid of the snow in time to play as scheduled.

Bills vice president of operations and guest experience Andy Major said Wednesday that more than 220,000 tons of snow would have to be cleared from Ralph Wilson Stadium before the game could be played. The team put out a request for shovelers, who would be paid $10 per hour and receive game tickets for their efforts.

Ryan said he had not heard about the possibility of the game being moved to Monday. The final decision rests with the NFL, which last postponed a game due to weather on Sunday, Dec. 26, 2010, when a blizzard hit Philadelphia and forced the Minnesota Vikings-Philadelphia Eagles game to be played two days later.

“Buffalo’s no stranger to getting snow,” said Ryan, who acknowledged he hadn’t seen the pictures of a region completely covered by snow. “So we’ll see if they move it or not, but if they do, that’s fine. We’ll make the appropriate adjustments.”

If Buffalo can’t practice in advance of the game — whenever it is played — Ryan said he thought it might not be such a difficult hurdle to clear for the Bills given the teams play in the same division and opposed each other just three weeks ago.

“Obviously, it’s not an ideal situation, for sure,” Ryan said. “But knowing the common opponent, their plan’s not going to change a whole lot (or) deviate from what it was the last time they played us. The quarterback got a 142 rating and they had six takeaways. I don’t think that’s going to change a whole lot.”

Actually, it probably would. What Ryan didn’t say Wednesday was the Bills cruised to a 43-23 win on Oct. 26 after Jets starting quarterback Geno Smith threw three interceptions in the first quarter. Michael Vick came on in relief with the Jets down 14-0 and committed three more turnovers.

However, the Jets haven’t turned the ball over in Vick’s subsequent two starts. It was the first time this season New York enjoyed back-to-back turnover-free games.

“I know if you turn the ball over, you’re not going to win,” Vick said Wednesday. “That’s always in the front of my mind.”

Ryan’s, too.

“We have to play a zillion times better than we did the last time we played Buffalo,” Ryan said Monday. “I think that is safe to say.”
