ALLEN PARK — With a 4-11 record, it seems likely the Detroit Lions coaching staff will undergo changes at the end of the season.

 Coach Jim Schwartz will keep his job and it appears offensive coordinator Scott Linehan is safe after Schwartz spoke glowingly about him on Thursday.

 “I think (Linehan has) done a great job. Again, I think particularly the ball security stuff. An offensive coordinator’s job is to put guys in position to make plays and I think over the course of the season we’ve been in good position to make plays,’’ Schwartz said.

“The fact that we’ve still been able to continue to get the ball to Calvin (Johnson). It’s one thing when all those other guys were healthy and you have a lot of other options, a lot of times people would say, ‘Hey you forget about Calvin a little bit when you have all those options.’

 “We really haven’t. Defenses have known that too, and they’ve taken the approach trying to take him out of the game plan,’’ Schwartz said. “Scott’s done a good job of creating ways to still get him the football, Matt (Stafford) has done a good job of delivering the football.’’

 Schwartz brought Linehan in as coordinator when he was first hired four seasons ago.
