Everything was in place to improve the touchdown when Sully decided to pull the sidestick, up to full deflection - Only computers prevented him to obtain better figures.
Everything would really have been in place if he had maintained more airspeed.
The computers might have saved everyone's bacon by not allowing an excursion into an AOA regime that might have triggered an AOA that was too high, at too high an altitude, with resulting increased rate of descent at water impact.
