Thank you for this post.
Through 86 games, which does not include last night's game, the Sox starters have thrown 49.2 fewer innings than they did at the same point last season. Also, their collective ERA is up 0.85.

Like you, I agree with everyone that the pen needs some help. However, the root of the problem is with the starting rotation. The failure on the starters' parts has a huge trickle down effect on the relievers. You just can't expect your pen to throw that many innings without having a negative impact, especially when the pen was built on the premise that the rotation would be a strong one.
