As I said, the PED evidence is circumstantial.
If you want to dig into the bad team-mate stuff, it's really all about the injury he had in 2004, and it's well-documented.
Nomar's behavior during that game was only one chapter in the story.
But even just sticking with the on-field aspects of his play that year, trading him was the right move.
He was, but for me he has two clouds over him, a PED cloud and a malcontent/season saboteur cloud. As a result he's nowhere near my list of favorite Sox players.
The one and only reason the #3 spot got downgraded in importance is that the stats show that spot comes up with two outs and nobody on more than any other spot. And that would be mainly in the first inning, obviously.
And it's easy to see that most managers don't really pay much attention to that.
