Really, really impressive. Cue Ron Paul.
MN is a good team guys. And, we’re in reach of PSU and WI. OSU and Bama are in a different orbit than everyone else.
Regarding OK yeah looks suspect but probably still up there as SP+ looks at different facets of individual plays rather than wins and losses as the human polls do. Sure, there is a huge correlation there but a loss doesn’t necessarily drop a team way down the list because it’s more about total body of work. It also filters out garbage time plays which is a fair number considering the number of blowouts in the Big Ten in 2019. From football outsiders:
Garbage time adjustments: The S&P+ figures used in the tables below only look at the plays that took place while a game was deemed competitive. Garbage-time plays and possessions have been filtered out of the calculations. The criteria for "garbage time" are as follows: a game is not within 38 points in the second quarter, 28 points in the third quarter, or 22 points in the fourth quarter.
