What do ratings do?

[GlennN]

Is there an explanation as to what the ratings mean here? Like, what governs the RB or WR propensity to fumble? RB's ability to find the hole? Route running for an RB (agility/speed shouldn't govern running as a ball carrier and running a route equally)? How about on defense - what governs ability to shed blocks? Ability to tackle? Is this like Front Page Sports Football Pro, where Intelligence and Discipline (and Aggression and Endurance) govern different things depending on the position? Hard to evaluate a roster not knowing any of these things. Spear, can you shed some light here? TIA!

OVR = Overall
SPD = Speed/acceleration of player
STR = Strength for tackling, breaking tackles
AGL = Agility for side to side movement.
END = Endurance related to speed, a tired player that is out of speed burst will be more prone to fumbles.
AGR = Aggression for decisions (example: QBs with a low aggression won't stay in the pocket as long)
DIS = Discpline for taking penalties
INT = Intelligence for decision making on offense and defense.
HND = Hands/Catching
BLK = Blocking
ARM = Arm Strength
PAC = Arm Accuracy
LEG = Leg Strength
KAC = Kick Accuracy
