Baynes should be able to continue through to 2019. I felt his 2014 WC performance was far superior, but also his role better suited his game. I'm not sure that Baynes was such a success at PF, especially as the tournament progressed. He definitely had struggles containing opposition stretch 4s. For me, it was a bit of a surprise that Lemanis went with Baynes starting at the 4 given his preference to use stretch 4s, but I suppose we don't have many options there with not enough frontcourt depth. The fact that Maric was 13th man says a lot about our frontcourt depth.
Without Bogut and Andersen, we are missing a quality stretch 4 and a quality rim protector: basically the two key ingredients in a modern frontcourt!
As Andersen is sure to retire, the closest to a quality stretch 4 is Motum. Do we have any promising bigs with range? I can only think of Maker, who at this stage is more in the category of "can" shoot the 3, rather than "reliably" shoots the 3. I've always liked Motum, but he has some glaring deficiencies. How much more can he develop after age 25? Hopefully Simmons somehow develops a nasty outside shot in the next 3 years.
I thought rebounding was a bit of an issue at times in this tournament, even though we had 3 NBA-quality bigs. Perhaps Maker and Simmons will help us in that regard.
I like Lemanis's tendency in selecting a defensive-minded lineup. Exum, Maker, and Simmons will fit in there. We really need those 3 to develop a lot more in the NBA.
