Lets look at his golds.
Relay 100m freestyle (he was riding on the wave of his team)
relay 200m fresstyle (didnt watch it but probably the same)
200m Butterfly (Who swims this event? Honestly 100meters is enough the last 100 they are buggered and swim it shitly anyway.)
Individual medley 200m (anything with breaststroke in =fail and anyone who can swim freestlyle or butterfly or backstroke wont give a shit about it)
Individual medley 400m (see above point)
Saying Michael Phelps is the best is as dumb as the americans saying they are world champions of nfl.
