just a little curious... why did you put lebron on that list? is he really 4th all-time already with game winners or something?
and really, you can't go wrong with any of the three of Bird, Jordan, or Kobe in crunch time. it would depend on situations though.
if you need 3s in crunch time, im taking Bird.
if you need a single shot from anywhere on the court, you can't go wrong with Kobe.
if you need someone to lead a comeback or to fend off an opposing team making a run through a 2 minute stretch (which is what i think most defines a clutch player, not game winning shots, because even a mediocre player like Rober Horry has hit a bunch of those), im taking Jordan.
but like i said, you cant really go wrong with any of them in crunchtime, single shot or a period of time.
