Smart 6'2" 46 minutes
Grant 6'5" 31 minutes
Timelord 6'8" 45 minutes
Romeo 6'4" 23 minutes
Smart is actually listed at 6'4", TL at 6'9", Romeo at 6'5", and Grant at 6'6". Naturally I assume that you will want to get those numbers accurate even though they support your argument less well.
Your point is a good one, though your conclusion is extreme.
I'd go along with you that height, and especially length, is an advantage in today's game. So is weight; but when the rules of NΒΑ basketball were changed a generation ago they elevated speed and skill to an importance that they hadn't had before, and the priority of speed has only increased over the last decade at least. Length is an advantage, and even weight is an advantage, if the player is quick.
Gone are the days of 'energy guys' and rebounding or shot-blocking specialists. You can't put guys on the floor that the defense doesn't have to guard; if you have to guard everyone the defense has to cover a lot of ground, and for that the modern NBA team needs speed.
You say that "We aren't winning anything with an NBA team with this vertically challenged team". While I can't go along with that extreme statement (there's more than one way to get there), I would agree that length is a good substitute for speed in most game circumstances. Even "speed" is more than one thing; it also includes anticipation on the defensive end, or - on the offensive end - the fine motor skills to fake an opponent. So as my ninth-grade coach used to say, it's better to be quick than fast.
I've been on here a few times urging people to pay attention to Toronto - as I'm sure you already are, since they're amazingly long. Now I realize that you're talking about height here, but I've seen you elsewhere talk about wingspan so I assume that that's in your thinking. I'm recalling you proposed trading Grant for Boucher for example.
The Raptors have the extreme version of length in the history of the NBA; not awesome height, but they've got a rotation's worth of 6'7, 6'8, 6'9" guys with 7'2" or greater wingspans. Looking forward to a Banton/Barnes/OG/Siakam/Birch lineup taking the floor. Only OG in that group is as short as 6'7".
But note something weird about the Toronto roster: they don't have anyone as tall as 6'10". Yes, a pro basketball team whose tallest player is 6'9".
The biggest problem with 7-footers in today's game is movement. It just takes time to get big thighs moving, to build up momentum to close out a shooter. Height is different from length because a lot of height means slower, usually, and especially because it means slower acceleration.
A while ago posters on here were lamenting the demise of the bigs battling in the low post that was one of the hallmarks of the game when they were first watching it. I recall one of them calling modern basketball a 'bad product' or words to that effect; I found it tragic, in a way, that anyone would be a fan of a team that played a game they didn't even like. But the rules that once made playing that way logical are just not coming back.
The wide-open game of today was re-engineered to showcase the skills and athleticism that is on display every night during the season; and the game has dramatically grown its fan base because of it.
NBA basketball is, more than ever, a game of movement, of speed and fine motor skills. Size, including weight, height, and length, are still advantages, all other things being equal - IF the player has speed and skills.
