I'll go out on a Limb and say Norris never takes an ab as a Nat, he seems almost too valuable not to be dealt, especially if his defense doesn't improve
Except that every single baseball source has noted that his defense already has improved. 40+% thrown out the last two years, great handle on the strike zone, just needs a little more seasoning on blocking balls and calling games to a pitcher's strengths.
Norris better not be in a deal for anything short of an established premier bat or a #1 SP.
Flores, once he proves he's healthy, seems like the most obvious choice to move.
