The specific trading scheme is: Raptors send Drazic to sign in the first round in 222, and get Sidious Young, Drew eubanks and the second round in 222 (from Pistons) from Spurs.
Actually, the Spurs have been searching for a deal about Yang since they got him last year, but they didn't expect to leave until now. The result of this transaction is still good, and I got a first round of signing, which can prepare for the next reconstruction.
After this deal was reached, the Spurs also quickly completed another deal, sending Derek White away, which was quite surprising. Josh Richardson, Langford and a protected first-round signing in 222 (the first four picks were protected), plus the first-round signing swap qualification in 228. Derek White averaged 3.3 minutes per game this season, with 14.4 points, 3.5 rebounds and 5.6 assists. For White, I believe that the Spurs fans are somewhat reluctant.
It is really rare for the Spurs to complete two transactions in a row, and they are making changes quietly. The past two seasons have all missed the playoffs, and they must change. The reason why this season has not been completely ruined is mainly to help Popovich, the old man, reach the first record in history. At present, Popovich has won a total of 1,33 games in the regular season, which is 6 games short of the 1,335 games beyond Nelson. This season is still very promising.
