Well let's look at the championship teams from the last 15 years
Warriors drafted Curry 7th, Thompson 11th, Green was draft in the second round, Lee and Iggy were signed as free agents, and Bogut was traded for by giving up a player selected in the second round (Ellis).
Spurs drafted Duncan (this the last team who won a championship by getting a star through 'tanking') 1st, Parker in the late first round, Ginobli in the second round, and Leonard 15th.
Heat lucked out when Wade fell to 4th, and signed both Lebron and Bosh.
Mavs lucked out by pick Dirk 8th and having a Euro player turn into a superstar. They filled their roster with free agents and trades.
The Lakers drafted Kobe 13th and Bynum 10th. They also traded for Gasol and Odom (Odom was obtained by trading Shaq, whom they signed as a free agent).
The Celtics grabbed Pierce at 10th and Rondo at 21st and traded for KG and Allen.
Detroit traded for Billups, Wallace, Wallace, and Hamilton. They drafted Prince 23rd.
Heat drafted Wade at 4th and traded for Shaq.
The Lakers drafted Kobe at 13th and signed Shaq in free agency.
Meanwhile, in the last 15 years, only one drafted in the top 3 has won a championship with the team who they were drafted by - Tim Duncan (unless you count Darko with the Pistons).
In fact, only 4 players from top 5 picks over the last 15 years have won a championship in that time - the big three with the Heat and Tim Duncan.
NBA champions almost always trade for stars and find gems in the draft.
But, by all means, "trust the process." It's a proven, time-tested method to becoming an NBA champion.
