Mattionals - I don't think what you outline would be the worst thing in the world - the team did win 98 games last year - but I do think that you are putting a lot of faith in LaRoche to stay healthy and productive and in Goodwin becoming a starting-caliber player better than Bourn or other outfielders out there this offseason.
If you trade Morse and start Moore, to me, that leaves you thin on the bench. Werth is older and LaRoche is older and one is likely to miss a chunk of games next year. I'd like to have Moore ready to step in when that happens.
