I have a spreadsheet that I would like to use to track the NFL seasons.
I'm having trouble figuring out the formula to use when there is a tie (either a 2-way, 3-way, or more). I have attached a screen shot of my spreadsheet. I have columns set up and I would like the ranking formula to be placed in column U shown in attachment.
I know there are different rules for ties within a division and conference, but I don;t know how to set it up in Excel. I'm sure it is a lengthy formula, so if there's an easier way to do it please let me know.

I've also posted this on answers.microsoft.com.
