Following two consecutive wins at Giants Stadium, the Bears were to finish a three-game road trip at Gillette Stadium against the New England Patriots. Similar to the week nine confrontation with the Miami Dolphins, turnovers contributed to the Bears' 17-13 loss against the Patriots.  The opening two quarters were a story of turnovers in a Rex Grossman interception by Asante Samuel, a Benjamin Watson catch knocked into the hands of Charles Tillman, a blocked Bears field goal attempt, and fumbles by Laurence Maroney and Grossman.   The third quarter saw a bizarre sequence of turnovers - first fumbles by both Watson and Reche Caldwell on the same play, followed by another Samuel interception of Grossman, and finally a second Tillman interception of Brady.   Through three quarters the game was tied 10-10 before a drive where Brady faked out Brian Urlacher on a nine-yard run ended in a two-yard score to Watson.  Turnovers then ended the game, with a Corey Dillon fumble followed by Samuel's third interception of Grossman.  Samuel's three picks tied Roland James in Patriots history for three interceptions in one game.. How many interceptions did Rex Grossman throw in the first half?
