Sure, guys are available. Ones like Florimon are available via waiver. Other guys are not; Escobar so far is in that latter category. Using, as you did, Florimon as some sort of evidence that Escobar is not of value ("marginal" or whatever) is just not valid. People have been banging sticks on the ground for a while now that Escobar and Florimon are interchangeable, but the minor league record says they are not, the transactions wire says they are not, and the evidence so far this season says they are not.
