Mike Reiss takes a look at the Pat's offensive line approaching training camp for espn boston. Reiss notes Logan Mankins was incredibly reliable; he not only started every game possible since becoming an Patriot, he never even missed a practice. Last year he had more snaps than any other guard in the NFL, and in the last five years has appeared in 98.8% of the offense's plays. The New England Patriots, lineman Logan Mankins haven't budged on contract talks - ESPN Boston If Kaczur struggles in making the switch to guard, the fallback plan probably would be to have five-year veteran Dann Connolly step in. Connolly started four games last season, filling in at right guard for Stephen Neal. It was the first starting experience of his career. Rich Ohrnberger (2009 fourth-round pick), George Bussey (2009 fifth-round pick), Ryan Wendell (2009 practice squad player) and Ted Larsen (2010 sixth-round pick) are farther down the depth chart but also possibilities to emerge with a strong camp. The Patriots have had a solid run at the left guard spot in Bill Belichick's tenure, with Joe Andruzzi, Mike Compton, Damien Woody and Mankins. All were solid contributors. Now another change is in the offing, and its impact can't be minimized.
