You shouldn't include insignificant variables. If they don't pass the 95% test (fairly standard) and have a t-value of 1.96 or more (with this number of samples) then they shouldn't be included. Furthermore a good analyst will look at the results and determine if the borderline variables are functioning properly. For example, does it make any sense for a QB to LOSE points as his stamina or spin move goes up? That formula says it does because you have included insignificant variables (some may be borderline and even included) and the results, while very minimal, make no sense. From all the tests I ran I included all variables and you could see fairly easily which ones were very significant and designed to be included from the nominal variables (like block shedding for a QB). I excluded the insignificant ones and only used the significant ones. To do otherwise would be a mistake imo. Remember, the computer is a whore for stats and if it can find any pattern to help minimize the errors it will, even if they don't make sense.

For example, here is the formula I came up with for QBs
Code:
Overall = - 63.1 + 0.146 Speed - 0.00005 Strength + 0.0321 Agility
          + 0.0327 Acceleration + 0.00100 Jumping + 0.358 Awareness

          + 0.0108 Trucking + 0.0120 Elusiveness + 0.00070 Stiff Arm
          - 0.00273 Spin Move + 0.00609 Juke Move + 0.00013 Carrying
          + 0.00004 Ball Carrier Vision - 0.0021 Run Block
          + 0.00529 Run Block Strength - 0.00544 Run Block Footwork
          + 0.0083 Pass Block - 0.00477 Pass Block Strength
          + 0.00741 Pass Block Footwork - 0.00180 Impact Blocking
          - 0.00757 Catching - 0.00139 Spectacular Catch

          - 0.00167 Tackle + 0.00040 Hit Power + 0.00136 Pursuit
