Below is a listing of 8 of the 9 sacks we allowed, with timestamps that correspond to the video. I've given my analysis (which is far from expert). By my count, I'd pin probably two of the eight on DR for holding the ball too long. There are a couple others that are questionable on who blame should fall on. There are at least four that in my opinion are clearly on the offensive line. Many of them seem to not be an inability to physically hold up, but a failure to communicate and ensure everyone is accounted for. There are at least three on this list where someone came in unblocked by a lineman, when they should have been. As you note, it isn't all on the OL, but even three where someone comes in unblocked is far too many.
1Q- 12:19 (1:03 in video)
Play action, bootleg. Tackled from back-end while trying to roll out. Lindenmeyer whiffs on block.
1Q- 0:28 (4:55 in video)
Coverage sack on third down. DR holds for ~3.5 seconds before he gets met. Was stepping up in pocket. Blocking was adequate for the most part.
2Q- 12:46 (6:20 in video)
Play action. Interior of line gets pushed back making it tough to step up in pocket. Right tackle gets moved back enough that rusher can get a hand on DR. Gets met by first defender in about 3.5 seconds.
2Q- 6:16 (8:29 in video)
Zero pocket on this play. Knaak gets absolutely beat up the middle. Forces DR to have to climb the pocket early to avoid the rusher. Allows edge rusher to slip back in. About 2.8 seconds between snap and first contact, but pressure got there well before that point.
2Q- 0:00 (11:14 in video)
Gottula just gets steamrolled. EJ is there to help chip rusher as he leaks out of backfield. Minnesota only rushes three here. If Gottula hadn’t been beaten on his one-on-one, Corcoran and Lutovsky probably give up a sack on the rusher they failed to block. About 3.5 seconds before DR gets contacted.
3Q- 12:00 (12:22 in video)
Minnesota sends 5 on rush, including two linebackers. EJ is able to pick up one of the two LBs, but the other gets by unblocked. With EJ staying in to block it is 6-on-5, but we have three lineman block the same guy and that’s what leaves EJ being left to block two guys. Pressure gets to DR in about 2 seconds. No pocket for him to navigate so he tries to bounce outside the pocket which was doomed for failure.
3Q- 1:01 (15:57 in video)
Minnesota rushes 4. EJ stays to block so it is 6-on-4. LB blitzes and instead of Knaak picking him up, he doubles to help Gottula. EJ gets absolutely blown up by the LB who has a full head of steam. DR has zero chance on this play. About 2.3 seconds between snap and when pressure gets there.
4Q- 10:11 (18:11 in video)
Minnesota rushes 6. EJ stays to help block, so it is 6-on-6. Gottula allows edge rusher to go unblocked, opting to instead wait to block the LB, who EJ picks up. Edge gets to DR in less than 2.5 seconds. Knaak and Evans double one of the rushers, so even if Gottula hadn’t picked up his guy, someone else would have gotten to DR unblocked, as well.
4Q- 0:00 (Last sack isn’t included in the video)
