FF TRADE QUESTION PLZ HELP NEED OPINIONS?

anyone owning jason witten will be very slow to give him up. he is one of the top tight ends because of his quarterback. i would say you had a better chance with the first trade because nobody will give up peyton manning for a reciever. also, willie parker may be easy to get because of his injury, but it may hurt you. when he comes back he may be good but the injury could come back and keep him out. i would rework the trade and try to give up some better players who you think will drop off in the second half
