Random quarter issues in BB could be a number of things. The game is based off RNG so theres a chance you just hit a stroke of bad luck in those quarters.
To my knowledge, the only quarter by quarter determinant is stamina and usually starts having an impact in the 2nd half if you play guys for long minutes, however it will get worse in the 4th too. I've seen many first quarters go great this season and then my team fall apart the rest of the game.
95% of the answers to questions pertaining to runs in games are just RNG screwing you...
