you should spend the low price for Mason.
I don't even have McCaffrey, but I grabbed Mason in one of my leagues. My opponent in that league has McCaffrey.
He shouldn't be expected to take the role like Elijah Mitchell would have, but he's still an obvious handcuff in my book because he cost nearly nothing.
Meanwhile, I have Kenneth Walker WITHOUT Charbonett, but the difference is that Charbonett is expensive.
