Ridley is an interesting option but I might not do it straight up let alone throw in a RB (assuming you are talking redraft). You can argue that Atl is so bad there will be lots of garbage time stats but the Chargers are a good team without much of a running game or a goal line hammer. If they are winning it's because of their passing game and Williams is looking more and more like the prime red zone, goal line guy.Nice, I was looking at Calvin Ridley hoping I could get Williams + a flex level RB. I was also looking at Waller for a similar offer (weird keeper league where I have Kelce and there are several flex spots).
Beyond the nice target numbers, which I think may not be sustainable at this level (but will still remain high), it's how the Chargers are using him near the goal line that really has me so high on Williams. Herbert really seems to trust this guy to go up and get the ball in big situations too.
