How could 4 of those 10 losses been wins? Pretty easy actually...
1) Game 1 vs New England. Bills force a punt, getting the ball at their own 20 with < 6:00 left in the 4th leading 21-20. 1st down run up the middle no gain. 2nd down incomplete pass stops clock. 3rd down check down pass gains only 4. Bills take only 1:20 off the clock and give ball back to Brady at his own 34 with 4:31 and all 3 time outs. Defense can't make stop, New England kills clock and kicks game-winning field goal with 9 seconds left. Overall in the 4th, Manuel is 3 for 6 for 20 yards.
2) Game 3 @ NY Jets. Bills tie the game at 20 with 10:47 left in the 4th after . Geno Smith hits Santonio Holmes for a 69 yard TD 3 plays later. Bills get 4 more drive starts in the quarter and only get as close as the Jets 46 yard line. Manuel is sacked 3 times in those last 10 minutes and goes 6 for 16.
3) Game 6 vs Cinci. Thad Lewis throws 2 4th quarter TDs to tie the game and force OT. Cinci gets into Bills territory but defense stiffens and they punt. We get ball at our own 7. 2 runs up the middle and an incomplete pass force us to punt from our own 11. Moorman booms a 51 yard punt but we allow a 29 yard return to our 33 yard line. Cinci kicks game winning FG 3 plays later.
4) Game 12 vs Atlanta. Bills up by 7 and force punt with 6:02 left in 4th. Bills run up middle loses 3 yards then an incomplete pass stops clock. We then get called for delay making 3rd and 17 from our own 3. 3rd down Check down pass gains only 14. Bills take only 1:36 off the clock. Bills defense has 3 penalties on ensuing drive including interference in the end zone before Atlanta ties game with 1:31 left. Bills actually move into Atlanta territory but Stevie fumbles at their 28 with :20 left on the clock. Game goes to OT. We get ball and complete pass near mid field but Scott Chandler then fumbles. Falcons go on to kick game winning FG 3 plays later.
I didn't even mention the Cleveland game where we appeared primed for a win but EJ got hurt and Tuel crapped the bed.
Patterns seen/lessons learned (hopefully):
1 - we can't hold a lead with the conservative play calling seen here. Runs up the middle and check down passes... no way to seal wins.
2 - defensive/special teams penalties/breakdowns at critical times.
3 - Early games in EJ's career (other than Carolina) he wasn't up to the challenge of these pressure situations.
