Some people would make a trade like that, such as newbs to fantasy who refuse to sit on players having slow starts and always are looking for players who are hot at that time but often unproven. This seems pretty legit.
Also, I know how you feel. I'm in a league where I feel like my team is really good, I have Kinsler, Reyes, Manny, Prince Fielder, Pedroia, and Billingsley, and Rios...and I'm in 2nd to last place. I've had some tough matchups and a lot of slow starts, but I think I have a pretty solid team.
