Prospal Strikes Lightning Twice

So last summer the Tampa Bay Lightning saw Vaclav Prospal abruptly split for the Mighty Ducks. He left so quickly, no one was even sure where he went.
Now, about a year or so later, he’s just as suddenly back in the Tampa fold (l:aphotoaday;p:aphotoaday).
The Ducks traded him back to Tampa for a second round draft pick. So the Ducks get to shed salary and Tampa gets to shed Cory Stillman, who Tampa brought in to replace Prospal.
Prospal was a powerhouse with Tampa. I never understood why he left so quickly. The only possible downside to his homecoming is that Tampa won the Cup without him. They ain’t broken, yet this seems to be a form of fixing. I can’t imagine Prospal will have any kind of negative impact on the team, though. Plus, Prospal took less money from Anaheim for a big signing bonus. So Tampa is getting him for less than they were willing to pay him last year with no signing bonus.
I feel bad for Stillman, though. Now he’s suddenly teamless.
