Why the Pats rotated at left tackle

In his regularly scheduled interview on sports radio WEEI, coach Bill Belichick explained why the Patriots rotated at left tackle in Monday's 38-17 loss to the Saints.

"We just weren't sure about Matt [Light] playing all the plays in the game," Belichick said, as Light was playing for the first time since injuring his knee Oct. 11. "I thought Matt did a nice job. He hasn't played in several weeks and to throw him back in there for every snap, what we didn't want to do was get into a situation at the end of the game -- in a close game -- that he would kind of run out of gas. So we tried to spell him and give him a break in there along the way."

The Patriots inserted Mark LeVoir at left tackle for a few series each half.

"Mark did a good job, Matt did a good job, Nick [Kaczur] held up pretty well over there [at right tackle]," Belichick said. "I thought Light, for as much time as he missed and the quality of rusher Will Smith is, I thought he did a nice job over there."
