Pedroia isn't going anywhere. The Sox don't trade guys like that, even if they slump hard in their 30's and everyone think's they're done (See:Papi,Big). Also, and this may shock the hell out of people...we dont know if Betts is good yet (See: Bradley Jr, Jackie). And even if he is, he's not blocked by Pedroia. They play different positions. If anyone's a threat to Pedroia is Moncada and word is he's good enough to play pretty much any position.
