I think the point Brennan is trying to make is that the overall league and team dynamics have not changed. 1,2 and 3 in our rotation (far more important than 4 and 5) still goes out there and has a decent start surrounding it not by mediocre starts but by heaping turds. 4 and 5 do what is expected of a 4 and a 5 which means they are already digging into the pen.
It is the failings of 1,2 and 3 that have not changed to any significant degree. Beckett is by far the most consistent of those three and to be honest I think he has fairly judged himself in that regard. He no longer believes baseball to be as important to him as it once was and the result is the occasional start where he simply is out there on the mound as an empty uniform. The most startling thing about that is that he is head and shoulders more consistent than Lester and Buch even given his current level of interest in baseball.
As for the league as a whole, the issue is not even where teams like the Orioles will finish at this point. In general there are more mid-level teams this year than there has been for a long time....those that are based primarily on pitching will last longer and win more games than those that are not which is how and why we go 10-3 in 13 games and still are mired in the basement.
The most important team dynamic bearing on the Sox is the Starting Pitching, most specifically 1,2 and 3. The most important league dynamic is the re-emergence of mid-level teams that will win more games generally and win more games from the Sox.
Those two elements bearing on the Sox remain essentially unchanged from the start of the year to today. There are other things both positive and negative to talk about including things the Sox could do better that might have an impact but as for right now, those two elements remain as the biggest issues bearing on the Sox.
If we are incredibly lucky we may end up bailed out by the league's second WC birth but that is about the only thing on the other side of the ledger. Interesting that the league waited till the season had already begun to finalize that decision.
