Predictions? Personally I see Ches as the light against the Death Star (NOP, Barega, so on...) in the years to come. IMO his career and wins still show him to have a ton of potential and growing room.
He clearly is a sub 13 guy but just hasn’t had any real competition yet... ie. running 13:08 this indoor solo while shoving people out of the way as he lapped them.
Of course this is a big statement too, but I see several Olympic medals, if not gold, in his future.
