They might have corrected it. I used it to verify my own memory from being at the game.
It's possible he initially went to the scoretable to check in at the same time as Kevin and Isaac and then got called back to the bench. Or someone entered it wrong and corrected it later? I bet that happens a lot. Anyway, when I commented during the first quarter that Keon must be in the doghouse -- that's what I was reacting to more than anything, the (erroneous) Colby Jones substitution.
Regardless, The Beam was lit in the end so all is right with the world.
