Absolutely ... because as Phan pointed out ... they ran the ball effectively in the first half. Charles went down early and they had no problems after that. Besides, when you're up by 28 points in the second half, it's really not about effectiveness anymore ... it's about chewing clock.
From the point that they went up 38-10 until the point that they fell behind they threw 18 passes**, 9 of which fell incomplete. An incomplete pass takes 5 or 6 seconds, whereas a completed pass inbounds or run can take (if you let it) almost 45 seconds. If we round the difference to 35 seconds, then that is almost 5:30 minutes of game time they "wasted" by throwing incomplete passes. Now, maybe it wouldn't have mattered because Indy went ahead with almost 5 minutes left in the game and timeouts in their pocket, but it is still bad game management, IMO.
**I could be off by a pass here and there, but it's something close to 9 for 18 during that stretch.
