Well, you're right if there are explicit blockers. In practice, it's more of in-betweens like "I can figure it out slowly" or "I didn't realize Jerry could help me just like that". When people encounter obvious blockers or they have no clue they will ask for help, but not so much for those "in-between". Another scenario that often happens to us is one task is being pretty much depended on, and if there's an "in-between" like I just said, it's likely to make the team run out of task for a while. People on the task may not be paying enough attention to each other's progress, leaving them in blind spots compared to the team lead. Stand-ups are great for spotting those problems and tackle them early.
