I didn't recognize it and I don't think I'm alone. I thought she was talking about how much Tennessee had won vs. how much everyone else had won. I'm sure Geno wanted to guide the conversation towards Natty's but I don't think that's what Muffett intended and I don't think she would mis-speak about it because she knows who's won what.
I'd bet the house she was talking overall program wins. If you listen to her words she doesn't mention championships. She said something like more wins than any other program. Truth be told she is right. TN has more wins.
