Please help - Why do only half my images lazy load while the rest don't load at all?

[ajsingh007]

Edit: I gave up and threw this in. Whatever. $("img.sgtBtn").trigger("unveil");

Live example at: http://www.nba.com/kings/sgt-dev

I have team logos in these elements and they lazy load just fine:
<img data-class="lazy" data-src="http://stats.nba.com/media/img/teams/logos/lac_logo.svg">

I have default buttons in these elements and they won't load. Why??
<img data-class="lazy" class="sgtBtn" data-src="http://i.cdn.turner.com/drp/nba/kings/sites/default/files/default_btn.png">

This is the jQuery I'm using:
$("img[data-class='lazy']").unveil();

I have attached the source of the page. Please help!!
