Re: Fantasy football trade
You always want the best player in any trade.
In this one that player is Colston, by a long-shot. At the end of the year, Colston will have 100 more points than Holmes. Colston is a Top-3 Wide Receiver.
I wouldn't do it, and instead I'd find another way to get a Running Back. After taking Crabtree, use your next two picks on Runningbacks. You should be able to get two decent Rookie Runningbacks that might pan out. You should also be able to find a runningback on the Free Agent wires that could help you.
Rule #1 in tradeology: Never give up the best player in a trade.
Try to get a Ray Rice for a Winslow, or Ronnie Brown straight up for Winslow.
