Clock issues and getting plays set was an issue with Russ for all of time here.
Stop trying to to John3 it up.
Re-read my post, and ask yourself who is responsible for the decision to hold Russ out of the preseason.
Hint, "Partners."
If you think I am John3-ing it, well, you don't know me very well.
Starting QBs who missed the preseason went 3-8 in week 1, maybe they should reconsider that idea.
I would suggest that some pre-season action would be even more important for a QB who has had game flow problems with his prior team, and is playing with a new line, OC, coach, receivers etc.
Even if the final say was not his, Russ should have demanded some pre-season time, to get in sync with the new team. Of course, that would require some self knowledge and reflection.
