Your Wrestling Challenge review today got me thinking of this one. We never did get a definitive answer as to why Tom Zenk quit, did we? I know Zenk said it was because he found out Martel went behind his back and negotiated his own higher paid deal. Martel (who to my knowledge has never denied what Zenk alleged) said it was because Zenk couldn't handle the pressure. Hindsight being what it is and assuming Zenk was right, he should've accepted Martel's contract and kept going. Who knows? Maybe Zenk could have gotten a decent singles push down the road.
I agree and I think Zenk threw away a lot of future money over petty nonsense.
