how is that an easily won endgame
However, white's king has to defend against the black g-h pawns, who will win against the one lone white pawn if it's left alone to defend.
In other words, the white king is overloaded. It has to protect the black king from invading on the a-rank and swallowing up pawns, and also protect the g-h pawns from walking down and queening.
Make sense?
