@Goodie's Guns has given you a much more detailed response than I would have, refer to that.
He wouldn't be my first choice, but he could provide short term value if you can get him in/out at the right time.
Still undecided on one of my trades for this round, whether I bring in a cheap defender while they are available or use up some of my cash for an extra premium defender to replace Chapman. Leaning to the premium option, just need to decide who.
