SpaceX delivered their commercial crew contract with 3 years delay, Boeing is currently on the 7th year of delay and running. NASA's SLS was delayed by nearly 6 years despite being conceived as the "easy and safe option" of combining shuttle parts in the shape of a rocket. Rocket science is hard, everyone missing their milestones is almost expected. And SpaceX is among the more reliable partners available to NASA.
