I had been mulling trading for Chapman for awhile, then Grey went ahead and ranked him 17 overall - so I decided to pull the trigger.
I ended up giving up Marco Estrada & Rymer Liriano for Aroldis Chapman.
I'm a bit concerned with Chapman's transition to SP and ability to be a legit starter (and his innings limit), but I think the risk is worth it in a 16 team H2H Dynasty League where pitching is really hard to come by.
But I could be wrong.
