When his dreams of becoming the next Steve Nash died, all Andrew "Taco" Caley wanted to do was write about sports, something he's been doing at Covers for more than a decade. A Journalism School grad from Holland College in Charlottetown, PEI, Andrew previously worked at The Chronicle Herald and Star Metro, but knew in his heart that his future lay in sports. He began at Covers as a news editor and has now done everything under the sun when it comes to content. His work has been seen on TSN, Sportsnet, VSiN, and CBS. These days Andrew's betting expertise is focused on his favorite teams; the Toronto Blue Jays and Toronto Raptors. He's also an avid college football fan and bettor. He can't be friends with you if you don't appreciate a Service Academy Under. You can also call him Covers Sixth Man, as he regularly steps up to guest host Before You Bet and our MLB and NCAAF release shows. The sportsbook where he does the bulk of his betting is bet365 thanks to its numerous prop betting options and competitive odds. His best advice? Find the balance between the numbers and what you see on the playing field. Then find the best price using multiple books. And don’t ask him where the nickname Taco comes from. It's not an interesting story. Seriously.<
