Fair enough - but there are comparable ones in Pujols, Mauer, D.Wright & Griffey Jr. You could even argue Crawford (coming off 5.9 and 7.7 WAR years), Ellsbury (who had a 9.4 WAR year and was coming off a 5.6 WAR year) and Kemp (coming off a 8.3 WAR year) are close.
Ironically, the best comparisons all completely fell off a cliff almost the day they signed the massive deal...
