Mr Boeing reckons that a 737-800 with a landing mass of 60 tonnes will stop in 5000' on a wet runway (autobrake 3). This assumes touching down at the touchdown point (on the sloping away runway32 at LBA?) I seem to recall LBA being about 7300 feet long. So when you add safety factors in for dispatch, it is getting limiting to LAND a heavy aircraft on a wet runway.
I have been told that other operators either have the short-field landing kit or fly 'less than full'...neither of which I can verify.
