The bigger question is in 3-4 years if the Angels are still struggling will Trout still want to be an Angel? I think the next 2 years will tell. Trout wants to win championships, World Series and if the Angels don't bring in players to help him then he will walk to the best team he feels can win it all.
So the plan should be to let Weaver/Wilson leave, talk Pujols into retirement, look to get the best pen, and then find a good lefty hitting left fielder. We might have a very good rotation with the current young pitchers so money should go to better offense and defense.
