As players they aren't much alike, closer to opposites than spitting images.
Lauri shot .423 from 3, Bender shot .277. Lauri shot .835 from the FT line, Bender shot .364. Lauri had a true shooting % of .635, Bender had a TS of .440. Lauri had an offensive rating of 134.1, Bender had an offensive rating of 86. And then there's the 25 to 5.3 difference in PER. Yes, one played a lot of minutes in college and the other played limited minutes in the NBA but saying they are the same is like saying water and fire are the same.
Bender shows signs of being an all around player when he fills out but shooting will likely never be his strength, defense will always be his calling card. Markkanen also shows signs of being a complete player but defense will never be his strength, he will always be an offensive threat more than anything. JMO of course.
