Gross.
I don't know of a better word to describe the effort by Corbin and the players.
This is on the coach, and this is on Vivek, not the players.
It's simple math, we've isolated the variable. With the same players, and a Malone as coach, there was unity, purpose and effort.
With the only thing changing being the coach, there is chaos, confusion, and no effort.
It's actually correct of the players to not give full effort when there is no cohesion and purpose on a team. A military needs a leader, if there is no leader, all effort is essentially wasted. So energy should be conserved, and risk should be minimized.
