Since the departure of RC and Charlie Weiss, it appears as if Patriots are unable to counter the adjustements made by the opposing teams during half time. In most of the big games they lost, they had the lead going into half-time, but they were unable perform at the same level in the second half. I recall this was not the case during the Patriots Super Bowl years. I don't know if it is due to lack experience on the coaching staff (OC/DC at the nfl level), different players or something else ??
