Prior is the most valuable piece in that puzzle. He's worth more than just Tejada or Zito alone. If the Cubs are losing Prior, Pie, Hill, Guzman, Walker and Dopirak, that is too much. Pie, Hill, Guzman, Walker and Dopirak is a lot to give up for a good but apparantly plateaud soon to be 28 year old lefty that is just 1 year away from free agency. Prior is clearly the better of the two pitchers, even though he's less accomplished. After a blazing start to his career Zito has hit a bump and had his two worst seasons back to back. But he's still going to make a killing in free agency. So anyway. Prior for Tejada? Cubs need to get more back. Pie, Hill, Guzman, Walker and Dopiral for Zito? Cubs giving up too much. Take one of those first three prospects off the table and we're talking. Remember, Oakland is losing Zito after this year. I don't see any other team trading them 3 prospects of the Pie, Hill, Guzman caliber plus a good cheap veteran like Walker and a highly touted but enigmatic prospect like Dopirak as a sweetener. Dope is the type of guy that would be featured in a lot of trades. The team that gets him will talk about how "just a year ago" he was their top prospect, and he's only had a minor setback.
