some of the stuff you read
reverse thrust would not be needed for a landing at either TEB or LGA...indeed, the great majority of stopping power on a dry runway is wheel brakes.
I recall doing power off glides in simulator training and landing on runway 33 at DCA.
As far as bailout options for going to TEB, interstate 80 approximates a left base all the way to the runway and could be used for landing.
This all doesn't mean that the hudson wasn't a good option...but it should make us all aware that we may have to make a tough decision and not to sit to dumb fat and happy all the time.
By the way, one could land gear up at TEB if the glide didn't permit gear extension.
