About "Cora just looks good," I agree the players do the heavy lifting, but this season Cora has been incredibly adept at managing a pitching staff that has four starters on the IL and one in the bullpen. He has also managed to avoid overworking the three official starters (Bello, Paxton, and Crawford) who are not on the IL--as well as the one in the bullpen. Same goes for the bullpen, which so far is also not overworked.
As for Bloom, you and others keep forgetting that John Henry has put a damper on spending big, especially for starting pitching. The Sox payroll is now 15th in MLB, the lowest (relative to other teams' salaries) it's been in the JH era and probably the last 40 years. Top payrolls right now are the Mets, Yankees, Padres, and Phillies, and none of them has a better record than the Sox. Phillies are tied with the Sox and the other three are worse.
