I think this should be interesting to watch unfold.http://espn.go.com/mlb/story/_/id/13089501/report-fbi-investigating-st-louis-cardinals-hacking-houston-astros-database
As a Cardinals fan, I hope that they are found innocent. According to ESPN, the FBI is close to a conclusion on whether or not the Cardinals hacked into the Astros, so we should know soon.
If the Cardinals are indeed guilty, this will hurt baseball, considering how successful the Cardinals have been recently. They have reached the NLCS 9 times since 2000, and have a good chance of making it again this year.
In some ways, this is similar to the Patriot's case of deflating footballs. In both cases, one of the most successful teams in their respective league was accused of an offense that was unlikely to make a major difference to the team. The big difference is that some of the officials of the Cardinals may face jail time.
Until the FBI concludes this case, we can only speculate. Multiple Cardinals officials could potentially face jail time. The Cardinals (the team) will likely be fined, but that should be the only punishment they receive. The fans of the Cardinals should be a bit worried because if this is true, it will harm the reputation of the Cardinals. The officials of the Cardinals are the ones that really have to worry.
