I'm going to try to inject a little optimism into this thread, not so much because I feel it, just as an exercise:
1) Assuming we keep Kimbrel, and assuming he improves over his Aug/Sep performance last year, the Sox have hands down the best bullpen in the AL. Depending on the bullpen they're facing, they should have 8-9 innings to score runs whereas the opposition will really struggle to score in close games after the 5th or 6th. That's a big advantage.
2) Andrew Vaughn's ceiling at the plate is higher than any other RF option available, and he showed last year that he's at least minimally competent in the field. Leury is obviously nothing spectacular, but he's proven that he can consistently contribute within the relatively narrow confines of his game. It is conceivable that, if done right, that platoon will offer nearly or more than the production of any other solution in RF.
3) No MLB team has an above average starter at all 8 positions...our 2B situation proves the rule.
4) The 4/5 spots (currently Kopech and Keuchel) in the starting rotation are question marks at best, but it's still a top 10 rotation. Sportsnaut has them at #3!
There, try that on for size, see how it fits. Maybe you'll find it's more comfortable than rampant negativity. I know I feel better.
