Francisco is very interesting. Horrible fielder. 9 errors in just 74 games at 3b. In 2013 he had a -0.7 dWAR.
And not good at getting on base. Last 4 years' OBP: .289, .278, .296, .300.
But very good power. Not elite power, but very good. In 2013 he had 18 homers in just 348 ab, and in 2014 he had 16 homers in just 287 ab.
He'll be 28 in 2015.
He is, in some ways, what we think WMB would be if given enough at-bats. Francisco has 30-hr potential over a full season. Can you live with bad fielding and bad OBP and put this guy in the #9 slot in the lineup and just let him whack 30 homers a year? Or could you live with this for a year or two until Cecchini is ready?
You could always slide Holt into 3b in the late innings for defensive purposes.
And the cost of this would be next to nothing. Which would allow the Sox to go get the two best SP on the market: Lester and Scherzer.
I actually think the OF defense, the IF defense with Napoli, Pedroia, and Vazquez, the improved offense from Cespedes and Castillo and Betts and (hopefully) Bogaerts can compensate for Francisco's bad D and lack of OBP. And holy crap the 1-2 of Lester and Scherzer would be amazing.
