Because the game still has no concept of pick protection. Even if you trade your own picks you can't protect them outside a certain position. Hence the picks are already given to the teams even if it depends on where they fall. Boston has the Mavs pick, Philly has the Lakers pick and it's also the reason why you can accumulate several dozen picks if you want to. I traded lots of guys out of boston and ended up with 7 first round picks in 2016 another 4 in 2017 and 5 in 2018 plus about 12 second round picks in 2016 and 10 in 2017. I traded all the stuff from 2017 and 2018 in and ended up with 16 first round picks in 2016 which I then traded in just before the deadline for the worst teams picks which means that in my Boston game I ended up in 2016 with the number 1, 2 and pick, the number 5, 6 and 7 pick and the number 9 and 10 pick. Plus I traded my number 20 and 26 pick for the Lakers first rounder in 2017
. The crazy thing about that is that, I don't know why, guys who you drafted, even ****ty guys, get like 1 or even 2 stars extra which means you can trade like hell for them. Since I basically traded away everyone in Boston and their eventual replacements apart from Bradley, Sullinger, Smart and Thomas and then had enough cap left over to sign Beal and Howard I knew I was set for life. I only kep Ben Simmons of my picks, traded Bradley, Sullinger and Howard and ended up with an 8 man rotation of only 80+ rated players plus another 10 picks
.
It's absolutely nuts that the game has no concept of the whole thing and even worse that the game apparently doesn't realize what you are doing. If any team would start stockpiling picks in the manner I did no team would offer them another pick just out of spite and they sure wouldn't trade in the pick of the worst team for 3 first rounders in 2017 and 2019
