With regard to the score, Mike, I'm not an actuary but it seems to me that the scoring system they used favored the defense. Plus Kiel played the entire second half and it was as bad as any QB play I've ever seen on my TV, so the score isn't all that relevant to me. (I'm not hating on the kid, just being honest. The kid has all the talent in the world and I'm not nervous about him eventually putting it together. Right now, though, not even close.)
On most of your other stuff, I agree. On the ball security stuff - it obviously has to get a lot better or even 8-5 is a pipe dream. Some of that is sloppiness you expect to see in a spring game, but it is still inexcusable in light of what went on last season. All of the QBs turned it over. In a real game, fumbles are worse than picks a lot of the time just because of field position concerns, but when our two experienced QBs continue to make the same infuriatingly bad throws (reads) that doomed them last year, that worried me a lot more than a botched snap from an inexperienced player. I'm much more confident in Golson figuring that out than I am about Rees or Hendrix getting better at not throwing it to the other team.
One other point on the turnovers: I'm not making an excuse for the players because there is none, but when we get down into the red zone I would really prefer we see less of the gadget-y pitch plays and reverses (fake reverses), etc., not more. The players should be able to execute these plays without putting the ball on the ground, but they don't. So can we please cut them out when we're in scoring range until they show they can execute them safely? It would cut down on the potential for disaster, IMO.
