Anyone here can relate to betting before the game starts and have worries about some questionable players to play?
The best example is for tomorrow's match, like Boston vs Phoenix, where J. Tatum is questionable to play. And Nuggets vs Bucks, like a Giannis and Jokić, are also questionable. Any advice?
When important people are questionable to suit up I never place a bet on the team. I mean you can just wait until some minutes before the game when the final roster available gets published, there are many fantasy sports sites that bring updates super quick actually. Also on Twitter teams often make a post about the starting 5 minutes before the game starts. That's the safest route. I had my fair share of bad surprises when suddenly some main guy didn't suit up and my bet was doomed before the game even started.

True, hard lessons for me in the past as well, I already put a bet and on the last minute, player A didn't suit up so obviously, my bet lost. So I just wait for the last minute to put my bet or even do some live betting as well so see how the game is.
Twitter is also one social media that everyone update in the last minute, not the player but the team itself. So could be someone that has inside information on which player are going to play and which one is going to sit. And personally, I do not think that Jayson Tatum is going to play against Phoenix.
Yeah its tough. Usually i wait until right before the game to drop the bet so i know who is playing and who isnt. The odds usually shift but id rather know than not. If a team is on a second game of a back to back you can expect if those players do play they will play significantly lower than normal. So possibly even worse it is difficult when lining up ypur bets early.
