The first pic of Dick Allen that comes into my head is always the one of him on the cover of SI with a cigarette hanging out of his mouth.
Dude was a fearsome hitter, but IMO, only to level of "Hall of Very Very Good". He fell off a cliff in his age 33-35 seasons. His 7 year peak is 40 and should be higher, and career WAR is short of 60. Yes, others with lower numbers have gotten in, but IMO, those were mostly mistakes. If he even had a couple of 2 WAR seasons in those last three years, that likely would have tipped the scales to induction.
