Sorry, uclabb... but somehow, when you score on nearly 50% of the plays, like you yourself said basketball is closest to... scoring's no longer a great accomplishment.
Take a touchdown; a team will take about 70 snaps, so about 70 plays per side a game on average... and with a final score, something relatively routine, like 27-21, that means one team had three TDs, and another had 3 TDs and 2 FGs...
So out of roughly 140 total plays, only 8 are scoring plays.
That makes those 8 all the more special... and the other plays, it makes THEM special, since you know they were BUILDING towards those few scoring plays.
Baseball- average score of 4-3 or 3-2 or so...
And that's out of a 150+ plays (pitches, pitch outs, stolen bases, etc.) a game.
So again, a few, they stand out, and the other built towards them, that single led to a souble which advances the runners into scoring position so the third hit of the inning can score that 1 run.
Hockey- speaks for itself, how many shots and by contrast how many goals there are.
And... yeah, there HAVE been great "smaller" basketball players, but generally it's a game for giants.
Baseball- doesn't matter.
Hockey- both big and small have advantages, so size isn't too big a factor.
American Football- it DOES help, size... but all sizes are needed, so if you're five foot six inches, yeah, you probably can't play defensive end... but kicker and punter and some halfbacks, they're that size... and conversely, if you're huge, you can easily play a lineman or alinebacker, but maybe not quarterback or halfback, something yu have to be smaller and more elusive for.
Basketball- unless your name's "Jordan" "Kobe" or "Magic" pretty much, you need a giant...
