Red Wings recent transactions?

Not that I doubt in Kenny Holland, but these recent signings are questionable. From what I hear, Hudler is leaving for the KHL, which is another hit to the depth chart, and now we signed defenseman Doug Janik, center Kris Newbury, right wing Jeremy Williams and defenseman Travis Ehrhardt. I hope these are some good players, and I would think they are if Holland wanted them. Your thoughts....
