It all depends on whom Lewis was matched against.

Fundamentally...Lewis would be like Foreman IWO...he wouldn't have lost his skills or his ring ethic...just probably a bit of movement & speed.

I think that Lewis could come back & win some fights depending, again, against who he faced...but honestly, all roads would have to end with a showdown against Wlad.

It'd be intriquing...but I don't know that Lewis could hold out long. If he came back...that would have to be the angle. A few warms up & then a Wlad fight & back to retirement.
