That's where GAR comes in. What GAR does is put career WAR in a historical context that takes into consideration both a player's career value and peak value. It starts with career WAR and adds a player's five-year peak WAR, multiplied by 1.6 to put peak and career on an equal scale. For a baseline, replacement level doesn't make sense -- typical replacement level is talent that's freely available, which just won't do when trying to separate the great from the greatest. Instead, we've chosen as the baseline the average of the 20th through 30th best at each position, that sweet spot at which you've stopped talking about inner circle Hall of Famers and started talking about the fictional Hall of Very Good.I read through that a few times, and... If you actually understood any of that, then your head is up Bill James's ass far enough for you to lick the twinkies he ate five years ago.
Remember when we rated players by watching them play?
