After watching the Jets’ offensive line underachieve last season coach Rex Ryan admits they had gotten away from dominating the point of attack and the physical style he loves. And Willie Colon — one of their new guards brought in to change that — said improvement isn’t just a goal but a necessity.

“This line has to be better. Not if we can we have to be better than last year’’ said Colon 30 a New Yorker making a homecoming with Gang Green. “We’ve got to be more efficient if it’s Mark [Sanchez] or Geno [Smith] out there we’ve got to protect him got to keep him upright and we’ve got to give them a chance to do their job.’’

The line didn’t do its job last year as the Jets were next-to-last in the NFL in sacks allowed per pass play and 23rd in average yards per carry. Enter new general manager John Idzik who added Bronx native and Hofstra product Colon from the Steelers Stephen Peterman from the Lions and Brian Winters from the draft to give Ryan the type of linemen he wants.

“They’re all the same kind of mentality — tough road grader-type guys” said Ryan who had Peterman working at left guard and Colon at right guard next to right tackle Austin Howard. “That also says something about your team. You bring in those guys because that’s what you want on your team. I like the way those guys are built.
