In a keep 4 I wouldn't trade Vanek for Eberle. Vanek as I'm sure everyone knows has been dominating and leads the league in points, I have no doubt he will cool off, but I think he's still a point per game player, and who knows how long he can ride this streak until he falls to a more normal PPG pace. Eberle is good but in a keep 4, I probably wouldn't keep him when looking at some of your other players. Vanek right now is the hottest player going, and to me that demands a greater return then Eberle, and if Vanek keeps things going at this extremely high pace, he makes himself a great keeper consideration than that of Eberle. To me this is keep Vanek, and I very much understand the concept of buy low and sell high, but this is not exactly that type of situation.
