I thought this quote was interesting
"What McDermott and Beane are interested in is putting together a team construct that leaves no one wondering how hard the man next to him is going to work during the practice week. There will be no doubt that each and every one of the 11 players on the field know their assignment on every single snap.
And that when the team is dealt a bad hand on or off the field, they won't fold."

Maybe it's just a case of certain players don't have the dedication and commitment that the new regime is trying to instill, and even though they may be talented, it's not worth compromising the integrity of what they are trying to do. So, poof, they are gone.
I'm good with that and since they were going nowhere special this year anyway, I'm fine with letting it play out.
