on the kansas city chiefs in miami. the chiefs haven't been to a super bowl for 50 years, but they have the best quarterback in the league, patrick mahomes. could he be the difference? this is so tough to call. both these teams are dynamic in their own right. they have stars on every side of the field. i'm just excited to be part of it and witness this greatness go down. the 49ers have a great running game. i love kyle sha na han, their head coach, and i love the way he calls plays. but, man, this san francisco 49ers defensive line is so dominant, the best unit in the game at that position and they are going to try to get after patrick mahomes. i tell you what, no matter how good he can throw, if he's on his back, those throws are not going anywhere. we'll be building up to super bowl 5a on the bbc sport website and if you're up for a late night it's live on bbc one with coverage starting at 11:25pm. margot robbie, renee zellweger
