What will the Welterweight division look like in a few years?

Crawford is getting on a bit and I could see him retiring at the top .Spence will probably move up to 154lbs as will Danny Garcia and Shawn Porter. Pacquaio will be done. Thurman already looks shot

Then there's a load of up and coming talent :
Alexander Besputin, Vergil Ortiz Jr, Jaron Ennis, Eimantis Stanionis, Radzhab Butaev, Ivan Golub, Josh Kelly, Paddy Donovan, Conor Benn, Shakhabas Makhmudov

Josh Taylor, and Regis Prograis and others could well move up from 140

I could see Josh Taylor take over the division in a couple of years.
