Graterol has a good arm, of course, but he has a career fWAR of 1.6 and bWAR of 0.9, so it's not like Bloom passed on a guy who's killing it. It amuses me how notin never fails to mention him. We all have our little obsessions.
OK, so let's look at Betts's deal with the Dodgers.
12 years
Year 1 started at age 28.5 ended at age 29
Year 2 started at age 29.5 ended at age 30
The last 10 of the 12 years are all over age 30.
Good signing or bad?
