Reading lines is ONE way tho win, its far from the only way...with all due respect sir.
Oddsmakers aren't from Yale or Princeton. I 100% agree that they are aware of situations, which is why some people see "fishy" lines. The reason most players fail is that they don't put in the work. If this game was easy, we all would be winning.
I try to find profitable situations that show a long term positive ROI at a minimum number, as well as consistent year to year winning seasons. Many of them involve the line.
Many here at the RX have dedicated threads with plays. Start a thread and keep an accurate record, hope you have a winning and profitable season.
