True. BUT, if you add Lillard, Deron, etc, to Hayward and Gobert, you take yourself from a building team to a contending team. In that case, a late first round pick hurts your flexibility when you need it most (approaching the cap). The 33rd pick becomes much more valuable than the 32nd pick.
Adding Deron doesn't do that. It just gives you a non-****ty option for backup PG. It's a minor improvement. Also, there is no "Lillard, Deron, etc". Those players are at completely different levels.
