So far I would say they have been "competent", but I'm not willing to give them much beyond that. They are just doing what was pretty obvious that needed to be done while the prior regime sat stuck in the "Twins Way." Shrewd would imply that they have somehow done something that no one was expecting, and superior to other orgs, and at this point I don't see enough to substantiate that. Sorry, but the OP is going to be favorable to the FO, and this sentence that we are dwelling on was just another example of that.
