He had inconsistent minutes throughout the season. Expecting a lot out of a 2nd round pick is setting yourself up for disappointment. Darrun Hilliard had a solid season for a rarely used rookie.
Before the Pistons' 2nd round pick was announced during the 2015 NBA Draft, I really did not know who to expect. It could have been a European stash player, or a young center to develop. When it was announced as Darrun Hilliard, I have to admit I was a bit disappointed.
Yes, it was only a 2nd round pick, but I had never even heard of this guy!
