Naturally the players are accountable, because they are the ones ultimately executing or not. So of course they carry their own burden with this. That being said, when you put young kids out there, in a highly cluster f game plan.....it not only breeds a culture of sloppiness, but it creates a false sense of taking over for certain guys. I'm sure every player on that court knows Hewitt is a bad coach, so I wouldn't be shocked if certain guys felt the need to take over on their own...which means even more reckless play. Look at Holloway and his shot decisions. There is just a total lack of control and discipline that has always been there from the top, so the players wouldn't expect different. You have kids Tom, what happens when they do something they aren't supposed to and you just pat their head, hand them a lollipop and giggle? Nothing changes. Same as when Hewitt witnesses mindless plays constantly, but yet doesn't move to enforce changes to limit them. Because mistakes happen, panicking happens, part of sports....but it's no surprise that a pretty lax guy like Hewitt has a team that's always been lax when it comes to the mental aspect of basketball.
Put them in a define system, and there will still be inconsistency. That is sports, but when you have a set group of plays etc....it takes a lot of the guesswork out of it for them. So again, it goes without saying that obviously the players have a hand in this, but given the tenure and experience of Hewitt....you'd think he would be a bit more mature and wise when it comes to handling college kids.
