If we are counting this preseason game as "an NFL game" than we have to count what he did last preseason. He went 27/46 (59%), 370 yards (8 YPA), threw 2 TDs and had no interceptions. I would say those are at least decent numbers.
Those aren't bad numbers at all. We never got to see him in a real game so who knows if he has improved from the KW days. Either way, I hope the best for Ryan as he never really got a decent chance. Hope he plays really well tomorrow and some team picks him up for a 2nd stringer.
