http://www.statenews.com Not a bad start, Spartans. Only you, Wisconsin, Purdue and Ohio State are undefeated in the Big Ten. You’re on top. But you’ve done this before. You started out 4-0 in 2005, 3-0 in 2006 — this isn’t news to you. You know the season isn’t won in four games. You know the season doesn’t really start until Big Ten play. en-us Gryphon 2.2.3b-tsn (woodward)/Foundry5 webmaster@statenews.com
