How many other 21 year old PG's are better than he is?
If Exum or Smart were available and DL thought they were the best player available, then you pick them anyway. Point guard is probably the most important position on the team and if one is big enough, then you can even play 2 together and have better playmaking potential.
No he is not "the answer", but he dman sure is part of the answer.
Very few players are "the answer". I'd put Jordan, James, Bryant, Shaq...and other similar level players in their primes as "the answer". Other wise it is a collection of players.
Until he turned 22 a couple weeks ago, I could have argued Kyrie Erving was a better 21 year old PG.
Why even bother wondering about this right now? I thought Trey had a fantastic year given the dysfunction of this season. I thought he had an even more impressive rookie season than Deron did. I saw absolutely nothing from this season that makes me want to push the panic button on Trey.
