From what I saw, Tyler was in foul trouble most of the night. He had 3 fouls at halftime and picked up his 4th not very far into the 3rd quarter.
You can't judge from just one game. That being said, from what I saw he got in foul trouble, stood around a lot and missed two crucial free throws at the end. Hopefully there is a lot more to his game than we saw, which I'm certain there is.
