Whoever looks at this and still says the team fell apart because of lack of heart is plain blind or a troll. Sometimes the team rolls or it falls apart and individuals try to look for the reasons inside of them but the only thing you might find in there is self-flagellation and as a result, they play worse. It's a vicious circle. If you don't believe me, look at the segments with Kessel or Gus, they can't even hide it, they're mostly angry at themselves.
Anyways, may next season be better, the potential is there!
