Wharton will never win a SX\MX Championship.
I understand riders fighting for a position in a turn. I'd say it's perfectly acceptable for them to bump into each other and even cause another rider to go down. It's the nature of the beast. This however is different from the only way that Wharton knows how to pass a rider. His method is ALWAYS to essentially mess up a turn, and use the rider he takes out as a berm.
Wharton will never amount to anything beyond what he has now if he keeps it up.
