I think people are concerned, me included, because we aren't getting competent play from our offensive or special teams units. The offence has improved but we started with the second to last ranked unit from last year, so improving to say 23rd in the league is a nice jump but still means our D has to hold teams to under 20 points to win, which isn't a good scenario. Our ST unit is still bottom 1/3 of the league, probably worse when the updated DVOA ranks come out tomorrow.
Could we beat any of those teams, sure. Would we be favoured to win any of those games, no.
