I would be surprised if Dombrowski was implicated.
This wasn’t a complicated plot involving camera installation and a live feed for signs. This was players possibly acting independently checking out video feeds to learn opposing signs and sequences. Since many of them have been plugged into something for a huge chunk of the last 10 years, it’s not surprising they wanted to see video. Not that it’s an excuse, but they might not even known it was illegal. You really can’t suppose that about the Astros. These two scandals are not apples and oranges; they’re apples and basketballs.
The only common thread is Cora, and he probably scoffed at the players doing this. “These kids today, thinking they know how to steal signs with their ‘video rooms.’ Harumph! In my day, which was last year, we set up cameras and banged garbage cans. And we liked it!!”
