Sacks

[22sec]

I'm still seeing QB designed running plays stopped behind the Line of Scrimmage counted as a sack.

Is the quarterback outside of the tackle box on these plays?
 
I don't know how or if the program determines what is a sack with a quarterback, but I will say that this may be one of those rules that the game may not be able to track perfectly without a lot of code.

I've seen it happen inside and outside the tackles. The thing is these are QB designed runs. I'm no programmer, but would seems like there could be something in there that says "If play is a Running play then 0 sack. If play is a Passing play then 1 sack" Again I'm soooo not a programmer[:D]

Are you playing on a Canadian field?

No, US-Amatuer

OK playing on a US-Pro field it works correctly.

Hmm okay.. I've checked the code and see that rule is only being applied to the US pro field type. Canadian, amature, and indoor field types are recording a sack regardless of the play type. It's not difficult to change but as far as I was aware only the NFL had that extra distinction on sacks.
 
As for what determines a sack...
 
Any tackle of the QB that happens behind the LOS is considered a sack.
 
Except on US Pro fields. On the 100 yard pro field, the designed play type is looked at as well. If the play was designed as a running play, no sack is recorded, even if the QB was processing passing commands and had to scramble or was just tackled.
 
This is a very important thing to remember when designing plays. When you create a play, a selector to provide the play type is shown on the Create Play Dialog. Not only does this play type selector set the default blocking style for the Offensive line, but it's also what the game looks at to make this extra distinction. So you could create a play with the play type set to run, set the offensive line to all pass blocking, send receivers out on routes, have the QB processing a PASS-READ command and if he's tackled, no sack will be recorded because you've told the game it's a designed running play.
 
The opposite holds true as well. If you create a play as a passing play, and have the QB roll out and run (or a QB draw or whatever else), then a tackle for a loss would be considered a sack because the play was designed as a passing play.
 
The play type is the only way the game really knows what sort of play it was supposed to be in order to make decisions in these cases. So it's important to be aware of.

In the NCAA, as long as the quarterback is in the action of attempting a pass (a pass play), it is ruled a sack. This is much like the NFL rule. Also note that if the quarterback is run out of bounds behind the LOS, the defender is credited with a sack in the NCAA. 

The NFL does remove sack yardage from the team passing stats, but not from the quarterback stats.
 
Sack yardage is not applied to the quarterback's stats in the CFL either.

In the NCAA, sack yardage is treated as negative rushing yardage and attempts in the quarterback's and team's statistics.
