Has Wlad indicated how long he plans to keep fighting? I don't look at Wlad as one of those HW's who attempt to hang on way too long. Nor do I think Wlad will ever make one of those ill-fated comebacks. So let's say for argument's sake that Wlad will fight until age 38. That would give him a couple more years to face some of those opponents you mention. Solis to me is a waste of flesh and bones, and is undeserving of a title shot. Mitchell is raw as hell... and I have my reservations about an ex-football player having any real shot at a HW title. He's likable and exciting to watch, but I don't picture him at the elite level. I had high hopes for Arreola at one time, but his meltdown against Vitali three years ago turned me off. Other than that, yeah.... it'd be nice to see Wlad systematically take on all the top prospects before calling it a career.
