Brandon Smith might be sucking in the big ones at Melbourne Storm training but it has nothing to do with fitness.

For 14 long days in a Melbourne hotel, the Kiwis hooker was not even able to inhale a whiff of fresh air.

Smith, 23, has opened up on the strict confines of his two-week Covid-19 quarantine that was arguably worse than incarceration.

No going outside and no balcony to sense the smell or sound of the world beyond the four walls of his hotel room.
