What difference does it make what position it comes from? Our offensive minded SS is gonna provide offense similar to that of an offensive minded 1B and our defensive minded 1B is likely to provide the offense of a defensive minded SS. Who cares that they come from non-traditional spots?
I would go further and say that I'd much rather be in the position of having a beast at SS and a lamb at 1st (offensively speaking), because it's a lot easier to make a significant upgrade from that position than vice versa.
The two are completely unrelated. It's great that we have great offensive production from shortstop. That doesn't mean we have to accept near-zero production from the least (or second-least) important position player.
We've been over this a thousand times and all seem to agree on this principle: there is an inverse relationship between the difficulty of a defensive position and the expected offensive production from that position. Doesn't mean you have to get low production from a hard position; DOES mean you HAVE to get production from an easy position.
Honestly what's so hard about that?
