Calculating ratings...

[HeatThreePeat]

how do u calculate a players speed quickness jumping and other skills you cant use the ratings machine for?

It's impossible to count players speed, quickness or jump. You just need to know how quick he is or how high can he jump to adjust those ratings.

If you can find some athletic data on a player like a measurement of their vertical leap or their time during a certain run, you might be able to come up with some good values to start with. After that, you just need to watch them and compare with other players and fine tune it.

A few generic standards don't hurt either. Generally speaking, point guards should have good speed, quickness and dribbling ratings unless they're noteworthy for not possessing great footspeed (like Mark Jackson back in the day) or being careless ballhandlers. Anywhere from 70-85 is a good range for those ratings for the average point guard.

Likewise, big, lumbering centres shouldn't have speed and quickness ratings that exceed 60. In fact, ratings of less than 50 would not be out of the question for some players. Being less athletic, such players should generally have lower jumping ratings, perhaps even in the 30s or 40s. More athletic players should have jumping ratings in the 60s or greater, particularly smaller guards who can dunk.

There are always exceptions and those should be reflected in a player's ratings but there are a few standards you can follow, at least as a base.

For kind of an educated guess, you can use some of the formulas i've been playing around with.

Speed: The fastest runners tend to be about 6'2" and 200lbs, so start at 100 and subtract 2 for each inch taller or shorter and 1 for each pound heavier or lighter. I also add or subtract about 5 or 10 based on reputation and how "in shape" a player looks. I also subtract 1 for every second year a player has been in the league.

Quickness: Smaller is usualy better here, so start at 100 and add 2 for each inch under 6'6" or subtract 2 for each inch over then subtract weight-divided-by ten(i,e; 230 lbs = 23). Again give bonuses and deductions to suit taste.

Jumping/athleticism: I use the same formula as speed, only changing the ideal size to 6'6" and 215 lbs. Note: I chose this size because this is the median height and weight of Michael Jordan, Dr. J., Kobe Bryant and Vince Carter.

Strength: Should favor heavy players with low center of gavity, so subtract a players height from weight -100. Example; a player is 6'8" and 245 lbs, that would be 145 - 68 = 77. Again add 5 or 10 for muscular guys, and subtract 5 or 10 for fat guys. Of course I have to consider 6'10" the same as 6'9", and 6'11" as 7'0".

Of course these are just starting off points, to give you a general idea of where players of certain sizes fit. You can always raise or lower from the base.

Example; a player is 6'8" and 245 lbs, that would be 145 - 68 = 77

You should just go by inches instead of rounding off. 6'8" = 80 inches, so 145 - 80 = 65. You can add a basic 10 to get close to your original value.

The thing about the Strength rating is it's hard to figure out what it actually effects on NBA Live. I believe the strength rating helps players make shots when they are fouled and helps their post defense, but I can't be completely sure.

Interesting approach OldFoolStyle, thanks for posting.
