Callaway for M. Williams in Dynasty

I have been offered Antonio Callaway for Mike Williams in a 1/2 point PPR dynasty league. I am on the fence. I like Callaway long term with Mayfield throwing him the ball, but Williams short term with Rivers throwing him the ball. I have Evans, Diggs, Parker, M jones, Westbrook, Gordon and Watkins on my roster now. Do I make the trade?

I like both. But man they targeted Callaway like 8 time and down field. He’s got the 4.4 speed and can take the top off. Big Mike seems like for him to be relevant he has to haul in the TD. I would like to see him get more of the target share. I dropped Big Mike for Callaway and Sutton. I feel more upside with those 2 personally.
