some dude was coaxing me and a buddy to bet against the high seed for a few picks in Vegas a few years ago. He said something along the lines that high seeds rarely beat the spread.  
  
 We were wasted all week and new to sports betting so it was mostly jibberish.  But he did say to put money down on Mercer over duke and what do you fucking know... missed out on an easy payout.

Yeah, the top couple seeds get really shitty lines in the first round.  They also won't let you parley them with other games on the money line
