Combine importance?

So I had a debate with a friend about the significance of the combine measurements and tests. He says it's over rated and a waste of time. I say no way, it definitely helps me out especially in the later rounds and also sorting out the undrafted rookie fa's. I think they're is going to be quite a few undrafted rookies who make it on rosters and have us scratching our heads in a few years like.. Wow how did I miss that? Here I compiled a list of combine tests. First the lane agility (under 11seconds). Shuttle run ( sub 3 seconds). 3/4 sprint (sub 3.24 seconds). I don't know, I just came up with this criteria as nba standard from looking at past nba times from previous nba stars/players I have posted at the bottom of the page to compare with.

If history serves correct.. One of the top three projected picks will end up being a bust. Never has there been a situation where all top three picks have been great that I recall. However, this also means that a star player or two and another 1-2 solid contributors will emerge out of the 4-10 picks.. My guess from looking at the combine results is Dante exum, Noah vonleh, aaron Gordon, Marcus smart, zach lavine. Gordon tested off the charts in every category besides the 3/4 sprint but then he also has almost a 7 foot wing span with 10.5 inch hand width.. and a 39 inch max vert. Noah vonleh on the other hand tested adequately athletically but he measured with a 7 '4 wingspan and a 12 inch hand width and a 37 inch max vert. Those are great numbers with preference leaning towards size and length for most teams. Couple of things I noticed was only three players made it on all three lists.. Zach lavine, Dante exum, and deandre Kane! What's crazy is Kane isn't projected to get drafted in some mocks and as early as mid second round. Quite a few got really close on this triple threat criteria, like Marcus smart, Scottie wilbekin, Jordan clarkson, aaron craft!... Etc.. so on and so forth. One player I'd like to point out is Markel brown I believe could've easily have made this list but he bombed on the lane agility, which I can understand since you can make terrible mental mistakes if your not familiar with the routine of the test. Another guy who I felt tested very well was cleanthony early.. 40 inch max vert! Along with impressive speed times. Also what's interesting check out kawhi Leonard's measurements at the bottom, he had only a 25.5 one step vertical and a 32 inch max vertical but has a 7 '3 wingspan and 11.25 width hands, so he didn't do all that well athletically besides the sprint but his length was impressive. Take a look.
