It's a pretty young team so I'm not too despondent. Was pleased with how Trubisky held up under pressure. Nobody expects him to be the new Dan Marino but it would be nice if we could actually have some stability at the QB position. Have some tricky looking games next season, though: Cowboys, Chiefs, Chargers, Saints, Rams, and the bloody Eagles again! Plus, I expect Green Bay to be back competing for the division title again next season. Not so sure about the Vikings/Lions, will see what they do in the off-season.
My biggest concern is our ability to turn close games into wins. Our five defeats this season were in overtime, twice, by a point, by a yard, and by a point/post/crossbar. You don't expect to win all of those sort of games, but a genuine top team should win more than they lose.
