I understand that. john used to play second controller on m80. im talking about maps like lotus and breezs where there will be double controller and a sentinel. he will need to flex to smokes. we all saw how sacy looked on controller.
Sen would never choose TenZ over Sacy for smokes, either they'll switch TenZ to duelist and zekken to smokes, or Sacy will just play smokes. Also, I think you're vastly underestimating how good Sacy can be on smokes if it's just for a map or two.
TenZ just doesn't fit the smokes playstyle, and unless he wants to adapt his game to be able to play smokes, SEN will not put him on smokes.
