Ex-NY Giants stud Barry Cofield will NOT go to jail after he smashed into cop cars last summer during a wild police chase while allegedly carrying heroin in his pocket ... TMZ Sports has learned.
As we previously reported, the Super Bowl XLII champ found himself in HUGE trouble after cops say they found the 34-year-old passed out behind the wheel of a Cadillac Escalade around 2:40 AM on July 3.
Cops say the 6'4", 250-pounder drove like a maniac ... ramming into cars and leading police on a dangerous pursuit.
Eventually, cops say they used a squad car to block Cofield in -- but he even tried to ram through that!
