Even so, if he lobs the ball to Fisher, there is no way that shot gets off in time. For Fisher to do what he did the ball had to be placed perfectly, as Payton did. Payton never should have had that clear look to Fisher like he did. A defender should have been in his face.
One thing I've often wondered about; when you have to make a key inbounds pass with only a tiny amount of time left - why don't more teams use their point guard to inbound the ball (as for example Payton).
The Point Guard is generally the best passer on most teams.
And you can't underestimate how key a good pass is. If Fisher had to fumble for the ball LA losses this game even if he can still get thw shot off because of the time remaining.
Wether or not he could have made the shot with a lobbed inbound is not known as that is not what happened. But the way you worded your post left a strong impression that because of the time it would take for a lob to reach the player the clock would expire during that time.
