You can't get stuck on any one player. It all comes down to the trade. Think about it this way: would you trade any one of those guys for Trout? Yep and happy to do it.
This could help land a free agent starter. Price and Garza would be good additions. Melky could DH and Gose, Sierra or Pillar in left. Defense in the outfield improves. Or Youk as an addition.
That's how we grew into world series contenders. We went from perennial 77 game winners to 82 or so to 89 and then boom. We tried to go from 74 to 90 plus. That's a big jump. A good manager would manage expectation better.
