Dolphins legend Bob Griese says he still pops champagne every time the last undefeated NFL team racks up its first L ... and he'll do it again this year, even if the last 0 standing belongs to Miami.
Remember, Griese was the star QB during that legendary 1972 Dolphins season -- when they ran the table and won the Super Bowl ... the ONLY team to make it through the regular season and playoffs without a loss.
Greise notes that the Patriots got close back in 2007 -- but couldn't close the deal in the Super Bowl .
