Interestingly the week opened with these two lines:Winston draft pick o/u: 3.5Mariota 1st overall: yes -400 no +300Within the day the Winston o/u was down to 35 and yesterday the 2.5 under was -130.Yesterday Mariota was -240 yes +240 no.Today the lines have been taken off the board.Looks like big bettors slammed that Winston line and are thinking he'll be first.
