So much for Ilitch is too cheap and Harris is too scared to sign or trade for expensive big leaguers. I would bet there's another shoe dropping at some point, although I'm not sure what that is.
Two immediate thoughts leap to mind:
This acquisition is definitely going to challenge an infield that is average at best, below average more likely. Valdez is simultaneously one of the premier ground ball pitchers in the game and one of the hardest-hit as well. There are going to be a lot of screaming ground balls getting through the infield when he's pitching, and we're going to hear Benetti intone "past a diving" a lot. To that end, if another shoe doesn't drop somehow, I would guess we're going to see a lot more Javy Baez at short this year, at least until his bat disintegrates.
I think a follow-on effect of signing Valdez is that overnight, Detroit has become a lot more attractive destination for free agents, because now they know we will pay players top dollar to come here. This is a big step toward moving ourselves into the conversation with the Big Six, Blue Jays, and Phillies when it comes to attracting top talent.
