That's the closest thing you have to a good point. I much prefer players to get their "revenge" by winning the game. However, while this play was dead, Youkilis did accomplish one thing by rushing the mound -- he got Porcello out of the game and replaced him with the guy we tied the game off of. Not saying that doing that was worth a 5 game suspension, but if you're going to pull out an argument that said it didn't affect the outcome of that game, it's pretty clear to me that it did.
I think the problem has more to do with how Tito replaced Youkilis than the actual suspension. We have a capable cadre of corner infielders with or without Youks, between Lowell, Kotchman and Martinez. Tito seems to have decided to use the suspension to get needed rest for other veterans (notably Drew), instead of putting the best lineup he still could out there until his star hitter got back.
And even in the worst case, there's still 45 games to go, we have Youks back, and we're still in position to make a move for the playoffs.
I don't like that he was suspended, but I just don't see why we need to invent a crisis over it.
