I backtracked and changed that to "he'd be eager". But you're right, "frustrated" is the right word for it. A guy who contributed positively for his team and still getting the shaft by being trade bait is probably really disheartening.
I should add: I read about Ryan's story a few months ago, and I have a lot more respect for the guy since. Not that I didn't like him, but I never really thought of him as having this troubled past considering that wasn't the story media played with (which is a good thing).
Definitely a good thing. I'm glad they're respecting that.
