tulsa had a great point about not listening to tv announcers....in the past when i really wanted to get a feel for a certain team's play i would just keep the volume muted and watch the game. it sounds strange but if you try it, you will be amazed at how quickly your brain kicks in and you start analyzing things you never thought about...
in NFL it's great because you start watching things that you normally miss...like offensive and defensive line surges.
during MLB, i hardly ever watch a game...so much of baseball handicapping is based on recent statistical handicapping (for example: L10-15 games played for team evaluations, and L5 starts for pitcher evaluations)...
very few subjective factors come into play unlike NBA, NFL and NHL (i.e. motivation, travel/fatigue, etc.) watching the games really doesn't help you very much in evaluating teams. there are a few exceptions, of course, such as learning which pitches a certain pitcher throws well which can help you later on in the season.
anyway, i'm definitely not one of the guys who has to sweat out each play....
that would be like me checking the price on one of my stocks every day...this is a long-term investment. not get rich quick.
sure, it's a lot more fun watching an NFL game than watching the price tracker on shares of a certain stock...
but if i can't see a certain late west coast game (i live on the east coast now) or if i feel i need to do more research on the computer instead of watching the game, it doesn't bother me one bit.
but everyone is different...whatever works best for you!
