New York Giants lineman David Diehl had a good time Sunday watching his beloved Croatia cruise to a 3-1 victory over Ireland in the Euro 2012 tournament. Perhaps too good of a time. As the giant Giant was leaving a Queens bar in his black BMW he sideswiped several parked cars, peeling paint, smashing bumpers and earning himself a DUI. When police arrived at the scene Diehl was passed out at the wheel, one witness told the Daily News. The lineman, a police source told the paper, smelled of alcohol and blew a .182 on the Breathalyzer. Now he faces up to a year in jail and a $1,000 fine, along with the wrath of the NFL, which counts DUIs as a violation of its substance abuse and personal conduct policies. Worse than the jail, the fine or NFL though might be the wrath his coach, the notoriously curmudgeonly Tom Coughlin, who sure likes to yell.
