No, you clearly aren't understanding consistent improvement. Claver was up and down, never consistently up.
Here are five examples of CONSISTENT improvement:
Jake Layman:
2012-13 - FG% = .396
2013-14 - FG% = .401
2014-15 - FG% = .470
2015-16 - FG% = .500
Jake Layman:
2012-13 - 3FG% = .299
2013-14 - 3FG% = .365
2014-15 - 3FG% = .378
2015-16 - 3FG% = .396
Jake Layman:
2012-13 - FT% = .694
2013-14 - FT% = .719
2014-15 - FT% = .752
2015-16 - FT% = .832
Jake Layman:
2012-13 - TS% = .510
2013-14 - TS% = .529
2014-15 - TS% = .589
2015-16 - TS% = .640
Jake Layman:
2012-13 - FG% = .489
2013-14 - FG% = .498
2014-15 - FG% = .544
2015-16 - FG% = .602
Notice how, in all cases, his shooting percentages are consistently improving from year to year.
The numbers you sited for Claver are the exact opposite of consistently improving:
.286, .377, .405, .320, .404, .364
He's down then he's up, oh but wait, he's down again, oh goody he's up again, oh crap, he's down yet again.
If you still don't understand the concept of consistent improvement, try importing the data into an Excel spreadsheet and graphing it. In Layman's case, all the graphs will show a line moving up and to the right. In Claver's case, the graph will look like a toddler trying to write the letter M for the first time.
