As of Wednesday, six weeks had passed since the home-platecollision that disassembled Buster Posey's left ankle. Posey was inthe Giants' broadcast booth, smiling andtalking about how the injury prevented him from taking care of hispregnant wife, Kristen, the way he had hoped. He seemed optimisticand confident, talking about how the premature end of his 2011season had reminded him how lucky he is to be a major-leaguer. Now that the gloom of those early post-collision days haslifted, a sober reflection on the Giants' campaign to improveprotection for catchers seems possible. In the initial weeks afterthe injury, excessive hostility toward Scott Cousins, the Marlinsplayer who bowled over Posey to score a 12th-inning game-winner,obscured the team's goal.
