I will agree, this is a preseason game, we aren't planning the parade route yet. However, one thing I will note, many of our starters did not play the entire second half.
I'll give you that our rookies were fresh going into the second half, and certainly in a better mental state then Winnipeg. However, I have little doubt Burke's halftime speach was to the effect "We're down, not out, if you want a job on this team, now is the time to show your character, step up and turn this game around." so I don't doubt they were hungry.
However, 17 unanswered points after the half against comprable players isn't acceptable for any team. Not being able to capitalize on a singe touchdown chance, or to even get into field goal distance for an entire half is brutal.
