So on your list, you left off Houser. I forgot; is Houser 5 for 5, or 5 for 6 in quality starts since the Sox signed him with that ERA of 2.27? Some one implied earlier that Houser is now of no more value than he was when the Sox signed him. That's ridiculous. He is much more of a commodity than he was when he signed with Sox.
Also let's discuss some people on your list.
Amaya was exactly what the Sox signed him to be: a strong glove and weak bat who would just hold a place until Colson came up. What the Sox didn't expect is that Meidroth was the one who took over at short for Amaya, not Colson. But again, Amaya was a good signing doing what the Sox expected from him.
Over and over again Stater and Tauchman have been great signings for the Sox this year. (Wait I don't see Tauchman on your list of signings. Hmm, it must just be an oversight on your part. Not your manipulating stuff to make your point?) Tauchman, pre-2nd injury was going to get the Sox a great flip, and Slater has done a great job. It could be argued without Slater, the Sox might very well have been swept by Toronto. In 1st win, he scored two runs and knocked in 2 runs. Yesterday, that walk was key, very key.
Taylor has also been exactly what the Sox signed him to do. Again, it's ironic that he's actually better than the guy he was signed to backup, so really, he's probably exceeded what the Sox signed him to be.
Wait why isn't Shane Smith on this list as an example of the Sox pro scouting. Again, I assume it's just an oversight on your part.
Also, what about Mike Vasil? That was a very good (great?) signing. Why isn't he on list?
What about Matt Thaiss? He was an excellent signing!! Held a spot in the lineup until until both Teel and Quero were ready to come up, and then the Sox flipped him for a quality prospect. What a great signing. Again, not on your list.
Now, of course there are some duds, as you listed above, but if you look at ALL of the signings, you have to be impressed with the Sox pro-scouting/ signings this year.
Hopefully your next bit will not have the oversights and omissions when you try to make a point.
