With the caveat that these are bold (i.e. unlikely) my reasoning for:
1. Exactly.
2. I expect Harper to have a big bounce back year. He was carrying an injury for much of 2016, had a higher WAR than Trout in 2015, and is still young.
If I had to put values on it I'd guess 8.5 for Harper. If Trout plays the full season he'll prob get at least 9, so this prediction prob relies on Trout getting an injury. Trout has mainly avoided injuries so far in his career so maybe this year he's unlucky.
3. Hopefully us, but if not someone like the Phillies who have their first pick protected.
4. Exactly.
5. If Mets rotation all get injured again, they could take a step back. Nats and Marlins driven by Harper and Stanton could have better years than the Mets.
6. I very nearly put Angels as the surprise contenders, but believe they're 3rd best in their division at best. Instead I think that they'll finally decide that missing the playoffs every year while having the worst farm in baseball isn't worth wasting the career of the best player of his generation.
