I understand that, but the premise is off IMO. I believe that OPS is the single most useful offensive statistic to measure how effective a player is. I realize thats open to differences of opinion, but regardless of where you place OPS, its certainly a very valuable statistic. The dropoff in OBP is also quite significant. Salty got tired through overuse last year. With catchers, it happens more than with probably any other position player. It happened to Varitek for the last 3-4 years of his tenure too. And it will probably happen to Saltalamacchia this year as well.
