Bills rookie wide receiver Sammy Watkins set career-highs with nine catches for 122 yards and two touchdowns — including the game-winner to beat the Vikings — the week prior to playing the Jets last month.

The speedster, who played with Rex Ryan’s son at Clemson and was the No. 4-overall pick in this year’s NFL Draft, wasn’t going to sneak up on the Jets.

“He scared me [at Clemson] and I wasn’t even working against him,” Jets defensive coordinator Dennis Thurman said heading into the Oct. 26 meeting.

After getting torched by Watkins for 157 yards — which included receptions of 84 and 61 yards, with the former 5 yards shorter than it should have been because of the receiver’s premature celebration — and a touchdown, the Jets would have every right to be terrified heading into Monday night’s game against the Bills in Detroit.

“After getting scorched by him, my feeling has not changed at all,” Ryan said this week. “He had like 150 yards against us, had the touchdown and then the celebration for 80 yards. I think it just kind of confirms what everybody in our building thought, that this guy was an outstanding player and a guy that doesn’t come down the pipe very often.”

Despite breaking an eight-game losing streak by holding the Steelers’ explosive passing attack to just one completion of more than 20 yards in their last game, the Jets are ranked 24th in the league in yards allowed per pass (7.7), while allowing a league-worst 25 passing touchdowns and tying for a league-worst three interceptions.

With the game moved indoors to Ford Field because of the devastating snow in Buffalo, the Jets’ secondary is expecting the game to feature more passing than anticipated at the beginning of the week, but safety Jaiquawn Jarrett said the team is also better prepared for Watkins’ speed this time, being able to simulate his abilities with Percy Harvin — who was traded to New York the week of the first game.

Cornerback Phillip Adams said allowing the rookie to run loose again isn’t an option.

“If shutting him down means winning the game, then that’s what we have to do,” Adams said. “He’s a great young talent and it’s going to be a challenge, but we’re going to do everything that we can possibly do to not let him have that kind of game again. We’re really going to be prepared for him to take away some of the things that he does.”

If only it were as simple as just stopping the big play.

Ryan, whose defense is ranked second worst in the league on third downs, allowing nearly 47 percent of attempts to go for first downs, noted the team’s struggles in those situations only complicates stopping the deep threat.

“You can’t just stay on top all the time,” Ryan said. “You have to challenge people, and usually we are a pretty good third-down defense. This year we have been horrendous. … There is that fine line. You can say, ‘Hey, just don’t let the ball go over your head, that’s great,’ but they are going to go 8, 9, 10 yards a click on you, and they are going to get it down there eventually. So, you can’t play defense that way either.”

Some way will suffice.
