Here are two interesting parts regarding A-Rod (http://espn.go.com/mlb/story/_/id/9540755/mlb-bans-13-including-alex-rodriguez-new-york-yankees-2014)
MLB commissioner Bud Selig said in a statement that Rodriguez's punishment will begin Thursday and cover the rest of the 2013 regular season, the 2013 postseason and the 2014 regular season and was covered under the drug program's protocols and based on Rodriguez's "use and possession of numerous forms of prohibited performance-enhancing substances, including testosterone and human growth hormone, over the course of multiple years."
The Yankees have said they expected Rodriguez to be accused of recruiting other athletes for the clinic, attempting to obstruct MLB's investigation and not being truthful with MLB in the past when he discussed his relationship with Dr. Anthony Galea, who pleaded guilty two years ago to a federal charge of bringing unapproved drugs into the United States from Canada.
That kind of supports that there was more to it.
