The Lions' interest in Barry likely is based on former Packers offensive line coach Larry Beightol's knowledge him. Beightol was hired in January as Detroit's offensive line coach and has coached Barry the last four seasons.
Barry played mainly as a reserve in the team's "U-71" package, named after his number, since making the team as an undrafted free agent in 2002. Barry often entered games as a blocking tight end.
The Packers probably are not making a big push to retain the 332-pound Barry because of their new zone-blocking scheme, which requires quicker lineman to adjust on the run to defenses. The "U-71" package likely will be banished under new offensive coordinator Jeff Jagodzinski.
Versatile veteran Grey Ruegamer and center Mike Flanagan are Green Bay's two other unrestricted free agent offensive lineman. Flanagan visited with the Houston Texans on Saturday, but left Sunday without a contract.
