Several points:

1. Kevin Garnett is entering his 14th NBA season.
2. Last night was Boston's third preseason game.
3. It was the second game of a back-to-back.
4. No one would have said anything if Rafer Alston scored an uncontested lay up in that situation.

Despite all that KG went for the block. Celtics fans should make sure they enjoy Garnett's time in Boston.
