He is a very good crosser, but I don't think it would be worth replacing what we have to bring him in.
He doesn't/didn't really offer us that much more.
You would also lose whatever speciality the other players have, such as Kaz's burst of speed, Buckley's straight line speed, or Orlandi's feet.
Conway did a decent stand in job, but personally, I wouldn't spend money on him when we have our squad.
