I don't understand this, Williamson is turd in the air and much weaker than Taylor, he'd get bullied to fuck and then start flailing his arms around grabbing at anything he could reach.
As people say, Taylor with a fit Colo next to him is far and away superior to Williamson, at everything.
I hope you're right. Too often I see Taylor nowhere near the big forwards and it ends up being Colo or Mbiwa who are going up for the aerial battles.
Because the big forwards will get next to the weaker CB. It happens all the time.
