An acceptable conclusion to any approach is a missed approach. But he would have needed to make that decision before touchdown - especially at LGA with a wet runway with a slight quartering tail wind.
Presuming that the airplane was properly configured: full flaps, autospoilers and autobrakes armed, AND that he had a stable approach: on speed and a normal glide path, he might have tried to "plant it" on the end and got a nasty bounce instead.
