The way he said it (trying to be exact, but can't exactly remember word for word.)

Q: Where can you play him (Burke)?
A: Well we liked him in the outfield, he showed his athleticism playing even center field-
Q: Second base?
A: Well, obviously when Biggio needs a day off, and shortstop...being in the outfield has helped his arm strength, where we think he could play there...he's done a lot of long-toss drills...so, he could be at shortstop. (pause) If there was an injury.

Was Purpura just thinking out loud? I don't think the Astros org ever projected Burke as an MLB shortstop.
It's probably best not to make too much of this, but it
certainly raised my eyebrows to hear him say that. Maybe he's shopping Burke as a shortstop, and those are some lines he's been feeding the other GMs at winter meetings? Maybe he means (assuming Viz is gone) Burke is 3rd on the depth chart at SS, behind Everett and The Brunt?
