Several very good points all in one PM...great level-headed post! Not just 162 either...almost 5000 total to choose from all season!
Long season and grinding will get you to the winner's circle almost assuredly. If you're backed into a bright red wall...lower your amounts and find multiple things to back the play you like or jump off. For instance, Oakland opened a favorite with Montas and flipped to Tampa almost immediately. Many will use this to make their move...I recommend finding more reasons and/or edges!
Always remember too...Vegas is still winning...pay attention to what they're "telling" you, where they feel vulnerable....use them to find an edge: the Reds with Roark on the ML are about +140 today...but Roark on the first 5 is closer to +115....hmmm
