The problem with going with a Mayer/Shaw IF is that there is a lot of risk that those two guys just aren't fully developed and will still take time to get there. Are they just leaning back into a youth movement? If so, might as well deal an OFer and call up KC too.
What if Shaw is just a guy who never hits in MLB and remains a below average fielder. That exit velo is scary. I would expect some improvement elsewhere.
Knowing what we know now, OCab was a bad hombre and had to go. Rentawreck was a truly horrible signing. Theo's crush on Lugo was clearly misguided. I will speak for everyone and say how we all loved Marco Scutaro and Alex Gonzalez. Gonzalez should have ben on the '07 team. Trading Scutaro for Clayton Mortensen was really dumb. Scutaro and Middlebrooks on the left side of the IF in '13 might not have cut it.
