What aspect of lindor's defense would improve with age? Instincts are hardwired and young players are at their peak from a physical standpoint. Defense hardly ever improves. The few instances I can think of are from some tweaks to footwork but usually they aren't drastic changes and they are few and far between.
Regardless this is all pointless as lindor is better than tulowitzki defensively ATM. If you knew about lindor you knew that his glove has been ready in the minors for a few seasons and they were just letting his bat Get to the major league level.
Again, this isn't controversial once you look at the facts
