Eh you can't really ding Beltran or Cora TOO much, that's unneccesarily sticking it to the Red Sox and Mets, who had nothing to do with it (and in the Red Sox' case they were also affected negatively by the Astros chicanery in the 2017 playoffs, let's not forget that, so then they'd be getting dinged on both ends for it). Fine em up the wazoo and make them each manage the whole season for free but unless evidence comes out they were THE mastermind(s) I doubt any long suspension should be in order. You want to give Beltran a nominal suspension for lying/obstructing the investigation well okay but it's hard to tell what's really 'fair' since there's no template for this.
Ultimately the hammer's gotta fall on Hinch and Luhnow, the buck stops with them...suspend them for a year, take away draft picks and international signing money for multiple years. You gotta find a way to put some teeth behind the punishment a la the Saints and Bountygate. Ding any coach still on the staff that was a part of it. I can't hold all the individual players responsible even though they all benefitted...if any of them were of particular interest masterminding it like Sal Evers on the '51 Giants that's something else.
