Jon Heyman had a little throwaway tweet a few minutes ago, where he mentions that the Astros "would have to be overwhelmed" by an offer for Jed Lowrie, but have talked to the Rangers and Cardinals about Bud Norris.
Bud Norris isn't going to help the Astros win a championship. And while he might be a #2 starter for the Astros, he's probably a #3-4 on most contending teams. So why not send him to a team with a deep system - even if they're within the division - for young building blocks?
