Depends on tempo they employ normally of course but I was thinking along the lines of 32 pass, 28 run and yes I would include scrambles of which I’d think would be around to 2 or 3 a game at this point in Rodgers career. Depends on OLine though. I saw a lot of good running lanes last year but the line makeup is going to be at least 20% different.
I wouldn't count kneel downs either. Scrambles are pass plays, kneel downs distort running stats, and Rodgers was good for about 3 per game combined last year.
If we take your split and knock it down one snap to 59 for a no-play kneel down, move 2.5 scramble snaps from the run play column to the pass play column, you get a breakdown of:
34.5 of 59 = 58.5% pass plays
24.5 of 59 = 40.5% run plays
I might quibble with that a little bit but it looks about right for what I'd expect. Of course that assumes the team is winning or tied in the 4th. quarter on a regular basis.
I'm seeing 1078 snaps for Rodgers and Boyle combined last season for 16 games, 67 per game. On that basis, throw out a generous 20 kneeldowns and you've got QBs dropping back to pass 620 times over the course of the season.
I'm afraid when some folks say they expect a 50/50 run/pass split they envision handing off to running backs for half the total play count with a mess of TEs on the field half the time to facilitate that. That ain't gonna happen, not even close.
