Think it will hinge on some big defensive stops and turnover(s). Niners D has been much improved this year but can they get to Mahomes the magician? His accuracy when extending the play has been outstanding in the play offs and the Niners will have to be at their very best to stop him. Equally the Niners run game has been strong and if they can limit the KC offence time on the field that would be a big plus. However, KC did a great job on the Titans beast last time out and therefore Jimmy G will need to find some targets to keep the chains moving. Great contest ahead I hope.
