Tocc has said himself he doesnt think all players need to “kill guys”. Again, if Kuzy was moving his feet, creating pressure and being in good position I firmly believe Tocchett would be happy.
You seem to think “hits” are measurably the same. 10 hits from Tom Wilson are not the same as 10 hits from PDG.
As for “quantifiable” - give it a rest. Eye test can easily show how engaged a player is.
