Thomas is a nice plug and play guy, and is definitely a safer lineup guy than McKinnon or Hawkins or Quick. You also seem to be set at WR, so you're really just hoping for a dominant flex option to emerge. In that case, I would go ahead and drop PT and grab McKinnon as a high upside guy. Know that there is risk here though, because Thomas should continue to get the ball, and we really don't know how much they're going to use McKinnon moving forward. I would gamble though, assuming you're using Dougie and Miami at the RB spot.
