Even if all three of them are 100% healthy for the rest of the season the roster construction is still shit.
You guys don't have a point guard in your rotation. Booker, Beal, Allen, and Gordon... they're all shooting guards. None of them have the necessary ball handling, vision, or passing to be full time point guards. Consequently the Suns' offense will devolve into Beal, Durant, and Booker taking turns going isolation or pick and roll. That's literally the only option the Suns have on offense because they don't have the point guard necessary to run advanced actions or sets.
