Honestly, I don't really get why people are so obsessed with how a player fit on a team over talent.
From what I am reading, it seem the only reason why people believe the Lakers should have traded for Buddy Hield over Westbrook is because Hield can shoot perimeter shots without taking anything else into consideration.
Based on what I have seen from Hield over the past 3 years, I wouldn't be confident that adding him to the team would be a major improvement especially if Schröder was to remain the starter and primary ball handler in this scenario.
I would much rather have Westbrook who can initiate the offense and take pressure off Lebron having to be the primary handler, lead the second unit when Lebron sit down, set up AD and other big men for easy buckets, and help pace both Lebron and AD for the entire season.
Beside, if you look at Hield's performance, you will see that his ppg, FG%, 3 point shooting have declined over the past 3 years.


Basically, if Schröder still remained the point guard or the Lakers couldn't find a better replacement for Schröder in free agency, then Hield is a nonfactor to me.
Now, if you add Hield to the current team with Lebron, AD, and Westbrook, then it would make sense to me and the Lakers clearly get better.
