Rizzo for Cashner will ultimately be better I would guess. fWAR as a Cub: Rizzo: 23.9 (6 seasons) Ramirez: 25.8 (8.5 seasons) Arrieta: 16.5 (~4 seasons) What we gave up in all 3 cases is negligible for the most part. Cashner has had the most success but he's been on several teams since the Cubs traded him. Sure, but that isn't including Lofton's WAR, and not subtracting Cashner's. But now that I think about it, the Sandberg trade and Sosa trade both prob beat Aramis. Right...Cashner has like 5.6 WAR since the trade. Lofton had 2.1 WAR with the Cubs in 2003. With Rizzo signed for 4 more seasons, its a pretty good bet that he will eclipse either of the other 2 trades
