possibly. the sad part is that a one dimensional ball basher storming the season isn't the worst thing to happen to the sport in recent years.
Of course it's not the worst thing, because it's not a bad thing at all, well on the contrary. Del Potro rising again and possibly even higher than he did back in the day would be great for tennis.
He's one dimensional, I'll give you that; but that dimension is great - unmatched power off both wings. It surely beats having guys whose only dimension is the ability to run a marathon on a tennis court in the top 5, no?
Realistically Del Potro might, I repeat might, challenge for slams in a couple of years when Nadal and Federer are no longer a force, provided he stays healthy (big if). As a fan I'll be happy if he keeps getting to QFs of big tournies with the occasional SF.
