First things first, two for one trades are always tricky as you are basically hoping that the other owner is dumb enough to trade quality for quantity. It rarely works unless the other owner is either new to FF or has a history of making panic/knee jerk reactions. YOU are acknowledging that Welker is NOT performing like a #1 WR and that Torain will likely be playing backup again once Portis is back on the field (likely to happen in week 11). YOU are fully aware that the FF outlook for these players is grim and you are hoping/assuming that the other owner doesn't read the same information that is available to you and everyone else. Chances are that the other owner DOES in fact know exactly what you know and therefor you aren't going to "pull the wool over his eyes." I doubt you can "snooker" him into taking 2 players based solely on what they did previously (in Torain) and projected (in Welker).
Second, you listed his RB's but not his full roster. I understand that you are giving him 2 players that will likely help hm but we really need his full roster to truly put ourselves in the other guys shoes to see if we'd make the trade (or to help you adjust your offer so that he may accept it). If you are offering him2 guys that will be starters on his tea fr just one current starter on his team AND tat the likely FF points generated from the 2 players you are giving him vs his one current starter (Moreno) and his scrub WR that Welker will replace is a good bit higher, only then does it really make sense for him to make the trade. Remember, if a trade makes YOU a good bit better but me only marginally better then why would I make the trade???
If you want one of his best players in a 2 for one deal then I think you are going to really have to knock his socks off with the 2 players you are giving him. A player likely to become the backup in 2 weeks and a player under performing just doesn't seem like enough to me.
