FOXBOROUGH -- A few quick hit observations from warmups:
Rookie Darius Butler lined up at left cornerback with the first unit. Butler has taken much of Shawn Springs' playing time the last two games, and there was some question as to whether that was to get him more experience or if he's passed Springs on the depth chart. If Butler starts today, as it appears he will, it would be a sign he's passed Springs on the depth chart.
As expected, five-year veteran Mike Wright lined up at right defensive end in the spot normally occupied by Jarvis Green, who is out after undergoing knee surgery.
Rookie Sebastian Vollmer was at left tackle with the first unit, where he's filled in for Matt Light (right knee) the last two games.
