I don't count decker as crazy like Tracy or the one captain of other ship who went ego crazy on roman world. Decker was one of best driven by guilt & possibly illness injuries.

Uh lot of tos didn't have a fundamental social message. And starship captain goes mad shows up several times within tos. The character interaction was spot on. In a way we got something we never got to see in tos. Why did kirk accept promotion when it clearly turns out to be a mistake.

They're also valuable because the players you use those picks on, including busts and guys who end up on IR, are cost-controlled. Your first round pick being injured is probably something you can work around. A player with Sauce Gardner's contract getting injured can be catastrophic.
