I want the Bucs to win, for 3 reasons:
1) I like Brady owning the record books wholesale, why not add some gravy to his incomparable resume and have him finish with a .70% winrate in the SB rather than a .60?
2) If the Bucs win, it's 7 rings for Brady vs 1 for Mahomes with him at 1-1 in the SB. Whereas if Mahomes wins it's 2 for him vs 6 for Brady, he keeps pace with Brady's early success, and the endless "Mahomes is the real GOAT" bleating gets much louder.
3) The last team to repeat was the Pats, I'd like it to stay that way as long as possible. I'm not ready or willing to hand over the title of the most recent dynasty to the Chiefs, and if they repeat, they'll get that crown on all media circuits on repeat whereas if they're one and done they're the most recent Seahawks instead, which seems about right for them, right down to the arc I'd like to see the team follow (continually failing to make it back while their team gets worse and worse until their star QB can't cover their deficiencies any longer)
I originally liked the Chiefs, during their rise, especially when Alex Smith was on there, felt like the 'island of broken toys', a bunch of castoffs from other organizations finding a way to win. Now that they have the newly anointed golden child of the NFL, it's a hard pass from me. I don't actually have anything against Mahomes either, I enjoy watching him play, he's a great player and has done and said nothing which has indicated to me that he's a terrible person. But he's the next Manning / Rodgers, where the media just can't wait to give him credit for the accomplishments he surely WILL do in the future, he's just so great and what an incredible once in a lifetime talent, there's no limit to the number of rings he'll get, and on and on and on.
