Trends yes but seeing as you lost by 3 points combined in two games that is so close it isn't a trend. You could easily be 4-1 if those go your way. I would sit tight.
I agree. I was faced with the same situation after week 3. Up to that point, most points scored in a single game was ~110. I had put up 98-96-97 for the first three weeks, and was 0-3. I received all kinds of trade offers, but most were people trying to take advantage of my 0-3 start. Which is most likely what you would be facing. I waited. It paid off. I finally received an offer for TO, that landed me Deuce and A.Johnson. So far, after the trade, I am 2-0, and looking good. Lesson? If the right deal comes along, make the move. But don't be so hung up on your record that you sell the farm. C.Brown is a very solid RB, and Harrison has as much potential as anyone out there. You could try and deal Brown, but I doubt you would get a WR/RB who will put up comparable points. Which leaves Harrison. He is underachieving right now, and I doubt anyone would give you a RB that would be an improvement over Brown or Edge. As for WR talent you could get for him, I don't think it would be anyone you would rather have over Harrison.
Put some feelers out there. Aim high, and see if people counter with anything fair. Like Detroit said, you could easily be 4-1. No need to anything drastic.
