By pool i guess you mean that the winner becomes a contender in line for a title shot?

If so, yes and no.

The trouble is there are no worthy challengers out there so presuming Solis beats Barrett he will be as worthy as anyone to have a title shot, as everybody else has already tried and failed abysmally. So in that sense yes.

However, clearly he is not ready for a world title shot in terms of realistically beating either Klitschko. Ideally he should continue to gain experience over the next couple years before thinking about going after either of them.

However the complete lack of talent and competition in the heavyweight division right now will likely necessitate the fact that he will get thrust forward sooner than he should, before he is ready, as there is literally nobody else for these guys to fight.

The old guard, the veterans, and those in the top 10 have all been smashed to the point where nobody wants to see them try again, and therefore the champs have to pick from the up and comers as nobody else is around.

It's a sad state of affairs really.
