Hi MHersh. I agree with the folks who already posted: you're giving up an awful lot. If your of is truly stacked and you won't miss Giles and Damon too much, grab this deal, but if your of would be in ruins afterwards, it's not worth it.
The less teams there are in your league, the better this deal looks to me. Also, if it's 5x5 (rather than 4x4) or h2h, that would also make this offer better for your team. What's the format?
