On another post I mentioned multiple improvements without giving details.
One of the improvements, and to your point, is his behavior the last few minute of tight games. In the past 2/3 months I have noticed that he does not appear to be "freaking out" when the game gets tight. Seems more in control/confident. Let's face it.....in the past he would call time out during a tight game and look like he was going to stroke out. Good to see the change.
Also.... depth and past reasonable concerns about putting a team together????? Aside from Yogi going out we do not see much decline with a lot of the subs. Injuries, fouls trouble etc....not good but this year we can deal with it. Very fun to watch.
