On May 5th 2019 the NTSB reported in their press conference, weather has complicated their efforts. The FDR was read out, preliminary information indicated the IAS at touchdown was 163 knots, 178 knots over ground (about 15 knots tail wind) at 30 degrees of flaps, ground spoilers deployed 3 seconds after touch down. The left hand thrust reverser was inoperative and the aircraft was dispatched under MEL.
If you assume a moderate landing weight and a wet ungrooved runway along with the preliminary data reported above, the calculated landing distance would have exceeded the runway available even without float and/or bounced landing.
