I think the Twins will hit, score runs and field at a very competitive level. Pinky and the Brain will have to scramble early on to address pitching.
I expect Berrios to improve modestly from last year. He needs to improve his stamina over the course of a year. I think he just fatigued out in the second half, despite his legendary workout routines. It was his first time at that many innings
I'm optimistic on Gibson because last year was a result of a complete overhaul in pitching mechanics and approach. Most importantly it came after scrapping the mechanics the Twins always forced on their pitching prospects. In fact other Twins prospects have adopted his routine in the off season. He may start a little slow since he is still recovering from his bout with E coli in the off season.
Assuming Pineda returns to career form, he should give is about 175 innings and an ERA just over 4.
Assuming Odorizzi returns to career form, he should give is about 175 innings and an ERA just either side of 4.
Assuming Perez's sessions with the velocity whisperer bear fruit, history says he could give us 185 innings with an ERA in the low to mid 4's.
If you add a good bullpen to all of the above, you would have reason to feel optimistic about the Twins prospects for winning a very winnable AL Central. The Twins don't have a good bullpen. The Twins don't have a mediocre bullpen. The Twins have horseshit bullpen and that's being generous. Even in the days when starting pitchers were men and could routinely throw 250+ innings this bullpen isn't good enough. As a result this about a .500 team until the Wonder Twins address this glaring weakness.
Baseball must be a wonderful game to survive the fools who run it.
