The 800/900 do land fast and it's uncomfortably at times, Boeings fix for shortcomings and stretching out the fuselage. Having said that this runway length should not have been a factor at all. Delayed reverser/braking with hydroplaning maybe. I know a lot more focus is coming down on briefing and discussing where the go-around decision should be executed if not planted on the runway. Easier said then done when the WX is ugly, the last thing you want to do is go back up and fly around some more.
