Brady is huge upgrade, Gronk is a good upgrade and i think Megatron might actually be worth AP+Jones
So i'd go with the deal, but it leaves you a little wounded for this week i think.
You need a TE and you lose pts from AP that Brady aren't there to pickup.
Anyway, it's a good move IMO and will leave you a lot stronger for playoffs, if you can make it there.
