If he goes to the Chiefs he's going to have a struggling QB and have to split targets with Kelce and Hill at a minimum. Why would he want to do that? If he wants to put up big numbers he needs to go where he's the best option on the field. And for that it would be the Saints.
Does he want to share targets with Adams and Cobb in GB while getting passes from a disgraced Aaron Rogers? I don't think so either.
