I don't know how anyone can fault the Steelers in this when Santonio gets on the internet and publically tells the world he's getting ready to smoke pot.
It's not great for trade leverage when the player has been arrested for marijuana before, among other things, and still feels the urge to get on a public website used by millions of people and say "wake n' bake :)"...I'm shocked at the stupidity, and it may have been enough to get him suspended for 4 games under the policy and drug code.
Combine Santonio's idiotic behavior with the fact he's a free-agent at the end of the season, and I think people are over-estimating his value. He's a major at-risk player who has the option of walking at the end of the season and he may miss the first 4 games of the season.
