I'll help you out, this is what I recall as I'm not going back to check
Detroit - Despite the come back definitely a winnable game in OT. Couldn't get the TD and Brock fluffed the INT. +0.5
Ravens - One of our best road games I thought. Lost by 6 but I won't count it as winnable even though our RZ conversions sucked.
Panthers - Definitely not winnable. One of our worst games.
Seahawks - See above
Bengals - Win
Falcons - Win
Giants - Win
Saints - No comment
Niners - While we only lost by 3 we were down by 14. It was winnable if we had a D though so I'm counting it. +1
Bucs - Definitely winnable. Scored 27 and were up late in the 4th. Defense couldn't stop a beach ball in a breeze. +1
Niners - Up again late in the game. Lost on one of the dumbest defensive calls I've seen. That zero blitz inside our own 30 on 3rd down. +1
Rams - Ugh
Steelers - When you can't hold Duck Hodges to less than 23 at home you have a problem.
Browns - Win
Seahawks - Win
Rams - Again up in the 4th and allowed the Rams 2 TD's for the comeback win. A couple of INT's and a bad D lettings us down. But winnable. +1
So conceivable with an average defense we could have won 4.5 more games which would have been 10-6.
