There's a thousand extra options we can ask to be put into the game, it's not realistic to micromanage every single second of every possession. What if the guy at 7 seconds was wide open with no one around him. Is he supposed to pull back and pass off so a guard can rush a bad shot 4 seconds later just so you don't give up an extra possession?? It's not uncommon at all for an offense to start the last possession around 10 seconds so there is a chance for a tip, rebound, foul is there is a miss, etc. Maybe the guard drove at 10 seconds, saw an open man, dished and he hit the shot. You should be screaming at the defense for giving up a game winner on the other end.
BTW I was actually going to agree with you until you said 7 seconds was the early part. I'd have a bigger issue with the guy taking the shot at 15 seconds, but as you see, it did give you the extra opportunity. If the shot at 7 seconds was missed and then there was an offensive rebound or tip and you won at the buzzer, I'm sure you'd have been OK with what happened.
