Let us get one thing straight, a QB should release the ball prior to or at the 3 second mark and most QBs do. I just rewatched the game and Rodgers had that ball out before 3 seconds on most of his completions.
Oldniner added it up and Smith gets quite a few of 2.8 seconds to throw a ball.
If you get MORE than 3 seconds, then you line is dominating. Most QBs get the ball out before 3 seconds hits.
Smith will get better but it's OK to admit that he's slow on his reads.
