I honestly don't. Span, Mauer and Morneau are excellent, but Kubel has horrible platoon issues, his counterpart is, well, Delmon Young, Thome can still mash but LHP can also neutralize him. Their offense will be highly productive, but it overachieved last year, and some their luck with RISP is bound to regress. A full season of Morneau might be just what they need, though.
I don't discount the possibility of them being better, but exaggerating to the point of "That might be the best 3-4 in baseball" simply to accentuate the "fact" that he tries to convey really irks me.
