Actually, I'm convinced that both sides know exactly how much "Go ahead and strike, but when you come back, we won't!!!" sentiment is out there...and the players union is thinking they can use this to their advantage for the very reason you stated above.
The players "short sightedly" think that the owners are still going to pay their salaries, even when you'll be able to fire a cannon through any major league park and not hit a soul.
Somebody needs to explain the concept of Chapter 11 and Chapter 13 to these guys.
An owner with any brains, (and trust me, most of them are pretty sharp...I know Colangelo is) will shutter the doors and file bankruptcy in a heart beat.
If they do strike, I suggest they work on their people skills.
They'll need it for when they are trying to "supersize" my soda & fries at my local fast food outlet.
