If we go down the current midfield + defence is more than good enough to come back up when you consider we've held our own against sides like Arsenal and Villa who would walk the championship.
£80 millions lost in revenue if we go down however I suspect the club held the Gordon fee back incase we did drop meaning only a £40 millions or so shortfall - you could fetch that with a Pickford or Onana sale or try keep both and flog Dominic Calvert-Lewin + Kean combined.
Simms is already scored goals down there and Dyche knows how to bring a side up.
1-2 forwards in with a few like Mina, Iwobi, Davies et al off the books and we come back up revitalised with a point to prove.
