Nope, it pretty much is must sweep.

As of right now, the only series that isn't "detrimental" to our PWR is the Michigan series. I quote detrimental, because every loss is right now.
Back in December, I said I felt the 'Cats
needed to go 12-4 in an effort to be well positioned in the Pairwise. That was just from eyeballing the standings at the time, and looking at where a 12-4 record would place their RPI rating. I estimated they would need to be above .555 and below .560. That may have been a bit "pipe dream"-ish, but it certainly was obtainable. Since my 12-4 declaration, the 'Cats have gone 4-2-2. To make math easy, figure the ties as a split each way, giving the 'Cats a 5-3 record.
As of right now going 7 of 8 puts the 'Cats solidly in where I said they could back in December. Going 6 of 8 should keep them as a three seed.
I know this team can do it. We've all seen the stretches of brilliance from them. This winning run starts tonight at the Berry.
