Well you made the same argument last offseason and the offseason before and the exact same thing happened both years as I had warned.
I get not wanting to spend 15m on a reliever, but they could also develop some young arms. They cut Estrada when he was going through some control issues and now he's a horse. They just traded Bigge and Leiter, and Effross before that. I get the logic of these decisions, but if they're going to keep putting such a low value on quality pen arms and trade most of the good ones away because Hoyer thinks they're "overvalued" they're going to end up with the type of pens they've had, which is mostly just a bunch of random dudes.
Real talent is real talent. Pedro Strop, Mariano Rivera, Josh Hader etc is real talent and are going to be good far more than they're bad. Extreme examples but if Hoyer wants to rely on luck then they're relying on a pen with a coin flips chance of being effective rather than stacking higher odds in their favour by acquiring or developing/keeping talent, and the results speak for themselves.
