If they sign Madson, as a fan I will be very excited, no doubt, in the end, any good player is welcome to improve our team.
The thing is, if they give him a large contract (something around Pap's one), IMO, it will not make sense at all, since you already had a better piece in Pap. On the other hand, if they sign him for a reasonable contract, will make sense.
As I said several times, Still I preferred Pap, even with the contract he got.
