His body language has been incredible. The way he shrugs off mistakes, his "dang, oh well" when he threw the pick to end the week 3 game almost entirely made up for the pick being thrown, at least for me. When he scrambled for a 1st at one point, then reached out for the Seattle player who tackled him to help him up, knowing that the dude wouldn't, that cracked me up.
He's cocky, but not amped up. Very measured. I loved the "finger gun" thing he did towards our sideline while he was rolling down field at one point. I've not been this excited for a Cards player since... probably Plummer, and when Plummer was making his first starts I was 14 or 15 and thought I was watching the next Montana. I'd like to think I'm a lil more down to earth now.
He has a gun for an arm, he can throw deep, he can throw with touch, he can throw with pressure and when given time he can REALLY make a team pay. There is nothing not to like thus far.
I want to be really clear about something I am about to say. I do NOT think Rosen is as good as Rodgers (I think Rodgers might be the best player ever and is tragically saddled with a bad GM and bad coach, who are only keeping their jobs because Aaron Rodgers is so damn good).
However, as far as the way he carries himself, Rosen reminds me of Rodgers. This casual cockiness. It isn't arrogance, but it is close. Willing to throw it into tight spots because... hey, he can and he know it, and when it works, he just kinda nods. At the same time, when something bad happens, he doesn't get emotional because... hey, he'll get em next time.
