Of your three issues:
Catcher: We acquired Saltalamacchia. Whether you agree or not, Theo believes in this guy and he will be breaking camp with the Sox next spring unless something goes wrong.
Outfield: Righthanded outfielders aren't as easy to find as you'd think, the outfield is the domain of the LHH/LHT because these guys aren't allowed to play infield. And the guys we have right now (McDonald and the switch-hitting Nava) are getting the job done about as well as most of the guys you could bring in to replace them.
RP: Frankly the team isn't close enough to a playoff spot to go nuts loading up the bullpen at this time.
See this is the problem with a general shopping list and the reason I'm pushing you into being specific. It's reall easy for a nonspecific list to be divorced from reality. I mean, why stop at a RHH OF, setup-caliber RP and a catcher? I'd like a 60-HR GG RHH 1B, a consistent .420 OBP leadoff bat and a pitcher with Bob Feller's velocity and Greg Maddux's command. And as long as I don't have to identify exactly how the team is supposed to fill my demands, I can sit there all day holding them "responsible" for failing to meet them, knowing full well that if I *had* to get specific the whole thing would become ridiculous in a real hurry.
