I think there's a lot in there. One of my takeaways:
While at the press conferences he seems to be a cliche "Every week 1-0, Every play 1-0" type guy, I think it's genuine and he really believes it.
While he celebrates the offensive drives with the guys, off the field he's poise and control. Most notably:
The missed PAT, check out everyone's reaction compared to his. Everyone is stunned or moan/groan about the miss, Russell seems to just note it, file it away, and move on to "What's next."
The Earl interception, everyone's cheering loudly (this was HUGE after all) but he's not cheering loudly and celebrating, Russell seems to just note it, file it away, and move on to "What's next".
The made field goal at the end .... all business still.
(and yeah, nice editing at the end there, be curious to hear what Russell's reaction was though..)
1-0, every play, every drive, every game.
