Not only is Lee solid with the bat, but he is probably the best defensive 1b in the game. Lee for A-Rod wont be a good idea. Lee is a great defensive 1b, but Arod's offensive value at short would outweigh Lee's value at first. Furthermore, Arod likely provides more offense than Lee and that would be from a position that offense is often scarce. Also, if we traded Lee for Arod, the added salary would only be minimal. The Cubs could attempt to trade for someone else to play first. Potential targets could be Todd Helton or Adam Dunn. I'm aware the Cubs won't trade Lee because of his popularity, and that view is extremely myopic. First of all, Arod has been and likely will be the more productive player. Lee really has only one great season surrounded by some good to very good seasons. Arod has been great for his entire career. Projecting outward, Arod likely will be the better hitter and considering he can likely play SS, his value is much greater than that of Lee. Finding a player who can even play SS at 75% of Arod's production would be very difficult. Finding a firstbaseman who could produce 75% of Lee's would likely be easy.
