I'm not sure they're bound to burn out, but it's the Mets, so I get what you're saying.
But, to me, this is a strong Mets squad that looks very together. 5 really good starters, arguably the best rotation in MLB, Ramos behind the plate, The Flying Squirrel leading the BA, Alonso having a Rookie of the Year season for the ages and basically leading the clubhouse, Conforto and JD Davis in great form... The question mark is Diaz and Familia and the Bullpen, which is what held them back before the break. We'll see.
I'm enjoying watching them though. If they can win this series v The Nats, anything is possible.
