In 2016 baseball, it is hard to put out a lead pipe cinch team. That said, I think this team has a ton of potential, with a bit less variability than last year. Ceiling is about the same as last year, but the floor is much higher.
The rotation? Well, Price is obviously going to provide some stability at the top ... Buchholz will be good, but obviously there is a question about whether he can be good for 150 innings. Rodriguez had issues turning over the lineup - but clearly the stuff is there. This applies double to Owens, who I think has gone from overrated to underrated as a pitching prospect. Porcello I think started to figure things out by end of last season. I am not expecting miracles, but I am expecting steady competence.
One thing that I will be curious about (and we won't learn this until the regular season) is whether the Red Sox start shifting their pitching staff management towards limiting "looks" the way that a lot of good teams were doing. That is, instead of just using pitch counts or what have you, start monitoring the pitchers the third time through the lineup and possibly pulling them prior to rotation #4 regardless.
Lineupwise? I am bullish on Ramirez at 1B. Getting healthy and back to an infield corner should help him defensively, and give him some comfort with the rest of his game. Hopefully whatever healing took place can restore his approach, which fell to pieces last season. There is a lot of awful defense you can put up with if it comes with a .900+ OPS. Ramirez' .300 OBP was a really big problem, but he clearly is a good enough hitter to get back to working counts again.
I am also bullish on Bogaerts who figured out how to deal with major league pitching. This season's challenge is to take the pitchers' pitches he sprayed to right field, and lay off of more of them - so he can get pitches to drive. He has conquered everything life has thrown at him, so I am optimistic - but refining his approach to get to his power is an important mission.
I am not bullish on Sandoval - but between Holt, and moving Ramirez to 3B, there are credible options to work around it. Sandoval's ability to make contact would be valuable - but clearly the onus is on him.
We'll have three quality outfielders - I wish I could tell you exactly who'll they be besides Betts.
