Let me start by saying (as Bob Huggins likes to say) that "You are what you are, your record is what it says it is." And what Michigan State & the Gophers both are this season is 6-6 and very mediocre. Coulda', woulda' and shoulda' doesn't mean a hill of beans. ... it's the loser's lament (referring to the "woulda', coulda', shoulda' excuse).
That said, here are some numbers through 3 years of the Dantonio-Brewster regimes:
Dantonio
22-16 overall
13-11 in Big 10
4-2 vs. chief rivals (Michigan & Notre Dame)
5-3 in November Big 10 games
2 seasons of .500 or better in Big 10 (including a 6-2)
0-2 in bowl games
0-1 head to head vs. Brew
Brew
14-23 overall
6-18 in Big 10
0-6 vs. chief rivals (Iowa & Wisconsin)
0-9 in November Big 10 games
0 seasons of .500 or better in Big 10
0-1 in bowl games
1-0 head to head vs. Dantonio
Other than the head to head meeting, can't see any way Brew wins this debate.
Thank you. Thank you. Thank you. Thank you.
