I'm a big Freeman fan but agree that simply hosting a playoff game is not in and of itself some amazing feat. It just means we finish in the top eight, which BK did five times in his 12 years ('12, '15, '18, '20, '21). If we host and lose in the first round (except maybe to like Georgia) I suspect a lot of us would be disappointed.
If we win a playoff game, and especially if we win two or more, that's a different story.
Regardless, no extensions until the last game is played. Doing otherwise is bad for business. I'd be very surprised if Freeman would push for an extension while the season is still underway, TBH.
