In 2013, he said about Kobe Bryant:

”Kobe can play at an extremely high level, in my estimation, for anywhere from another three-to-five years.”

Tim added:

”The way he takes care of his body, the way he takes care of himself mentally, the time he puts in.”

For Tim, there are three types of competitors: Coolers, Closers, and Cleaners. They are described as follows:

  • a Cooler follows others and is hesitant to take initiative;
  • a Closer completes the required tasks and enjoys being congratulated afterward;
  • a Cleaner stops at nothing to achieve the end result. 

Tim further explained:

“Cooler, Closer, Cleaner… good, great, unstoppable. You can be whichever you want. If you want to be unstoppable, you’ve got to make the commitment.”
