It stands at 26 games and gets a mention in this ESPN list.
It's hard to believe it was back in 2008 against EMU in Ypsi when our punter/holder, reacting to a blocked FG, picked up the rock and gained a 1st down. Otherwise, the streak would be longer. Harder yet to believe, the Zips won a FEW road games that year, including one in the Carrier Dome (as a few of us witnessed).
