It's not a binary choice, though. There are other ways. The way we've used to build every Jazz team worth anything the past 40 years, for example. Work with what you have, identify talent, obtain it by any means necessary. The Jazz have had fewer top 5 picks during their existence than I think any team in the NBA. Hasn't stopped us from building some decent teams over the years.
Gobert and Mitchell for mid and late first round picks, and neither of them were actually drafted by the Jazz. On a complete tangent, can you imagine this Denver team with Mitchell instead of Murray? The man who we can now say was easily the third best player on that team was undrafted. We picked him up as he was about to board a plane to Australia. There were a few top-5 picks on that team but they were all role players and we obtained most of them in trades. The one we drafted ourselves had no bearing on our wins and losses one way or another.
When it briefly looked like we might have a decent team led by a goofy, white kid from Indiana, the kid in question was drafted with a 9th pick we obtained a lifetime ago in a Tom Gugliotta trade.
The late 00s team was a motley crew if you've ever seen one. Our own draftee(though we traded up to secure him), 21st pick in the draft selected behind such luminaries as Frederic Weiss and currently-in-the-news Trajan Langdon, and two small-time free agents. One of whom we should never have been able to sign, but he decided to screw his original team owner. Is it still too soon to crack that Boozer and the Jazz robbed Gund blind?
I see contours of something like this right now, as well. Lauri was an amazing find for someone who was really a throw in as far as that trade was concerned. Sexton is the type of energetic, undersized guard the NBA seems to be full of, but he's shown signs of being able to make the leap to the next level of Brunson/Mitchell kind of play. I still think Kessler will develop into an All-Defensive kind of center. All 3 rookies look like they can hang in the NBA, at least. George looks like he will easily outperform his draft position. We've got the second biggest pick haul in the league over the next 5-6 years. There is zero need to tank right now, when even if you finish with the worst record(and boy, look around...it's not easy), you only get a 14% of getting the first pick. The benefits are minimal.
