Parker easy money. At worst he costs to a lethargic points win. But he probably puts it together on the night and stops Wilder.
Wilder by decision. Parker has the physical tools and durability to beat Wilder, but his skill set leaves a lot to be desired. Wilder would most likely out land and outpoint Parker.
Wilder always has a Windmill's chance but if Parker is up for it he is skilled and intelligent enough to avoid the one trick pony right hand and school Wilder. I'd go for Parker UD if on neutral territory.
Wilder lands a KO bomb on Parker's head before Parker can land enough concussive punches on Wilder's head. The fact Wilder's arms are about twice as long will help him land first.
I'd like to see it, for a host of reasons. (seeing Wilder face a big old SHW that can box and punch, for once - and isn't geriatric; and seeing Joe have a fight he can "get up" for, instead of this half-ass drudgery rut)
Don't think I'd pick Wilder to beat any top 10 heavyweight on points, unless the fight was absolutely littered with knock-downs and the opponent was seriously chinny
Parker would go into his shell once he feels Deontay's devastating power, similar to the Whyte and Joshua fight. Even Ruiz started coming on strong when he realized Joseph isn't the most concussive puncher. Wilder by UD.
