Haha, I think those are xbox prices, but either way... it's not like your offer was crazy. Though I know you know that now.
Eberle's price is high because he's fun to play with. He got a rare +5 on his SOTW boost, he's a speedy dangler... he's part of a really fun line to use... So many things work in his favor. Benn is a big time fav of mine, but even I know he can't touch Eb's price.
Name > Skill. I can go get a Nathan Horton for 10k, who is an 87, or Pat Kane for 37k and he's an 84.
Kane is a great card though only his defensive abilities lower his overall I would take him over most 87 overalls.
