Since ANY player you pick up in the Rule 5 draft is, by definition, another team's rejection, I presume that means you would have the Twins not draft anyone in the Rule 5 draft, I gather. I respectfully disagree.
I also disagree that "every" blogger who's talked about the bullpen predicts he will make the roster. That said, you stated in your prior post that you're surprised everyone assumes Doyle will make the roster out of ST, and now you say that you fully expect that to be the case. Since it sounds like you are one of those who assume that will be the case, you probably shouldn't be surprised that others do, too.
For the record, I'm not one of them. I expect them to try to work a deal with Chicago to keep him in the organization, but I also maintain it's far too early to assume anything with regard to him.
