If Betts is potential Top 10 btw, it is only because I assume there are 10 better player in the league - there might not be this year, and there surely won't be the next few. Again, for the right guy you listen - an ace sort qualifies.
Kluber is an interesting one - because the Guardians have a lot of starting pitching. One of the Mets starters is another (although clearly Harvey would have been the most likely and we know how that is turning out). Sale, Quintana etc.
I would also advocate (at a lesser price) to see if you could make a sneak attack and nab Verlander - who is more expensive (duh) but really damn good. I'd even call the Rangers on Darvish - but they are about as loaded with young positional stud talent as we are.
And yes - I am also betting the under on Bradley for next season, although I expect him to be a solid starting CF for his career.
