I’ve read a number of dissenting opinions in recent months on the Toronto Blue Jays daring offseason acquisition of Cy Young winner and best-selling author R.A. Dickey. A number of Dickey’s detractors have cited concerns over his age and his transition to a far more dangerous division and league. If Dickey does manage to perform well for the duration of his contract with Toronto, however, he is certain to pass some historical milemarkers for players reaching their potential in the back end of their careers.
