Actually, this is not the case at all on basic runs. There the responsibility is crystal clear black and white. In a 3-4 defense, the front 3 are primarily responsible for keeping the line stable and keep it from 'spreading' (for purposes of this discussion). If they do this successfully, this usually leaves a possibility for two inside gaps - one over the OLG and one over the ORG. These gaps are THE responsibility of the ILBs. Think about it - there is NOONE else in position to stop a RB for a gain of less than 4 yards. In the 3-4, if one of the DL is able to work off of his block(s) (many times double teamed) and make a tackle or slow the RB down, this is a bonus, but NOT their primary responsibility.
Um, I'm not following you...
Gaps = spaces between offensive linemen and tight ends, or where this spaces would be if a player was lined up to that side.
The 'A' gap is the space between the center and the guard to either side, hence 2 'A' gaps. The players responsible for those gaps in a base 3-4 are the NT and the 2 ILBs.
The 'B' gap is the space between the guard and the tackle, again 2 'B' gaps, the players responsible for the 'b' gaps are the ILBs and the DEs.
The 'C' gap is the space between the tackle and the tight end (or the area that would be a space between them if the TE was lined up on that side). As before, 2 'C' gaps. The players responsible for the 'C' gaps are the DEs and the OLBs.
The 'D' gap is the space between the TE and the flanker. It's rare that a team lines up with two TEs and two flankers, but you can see it. Those 'D' gaps are the responsibility of the OLBs, and a DB, either a S or a CB.
Put simply, there is no "gap" where an OLG or ORG is, that is a 300+ lb. trench warrior. Perhaps this is how you and I see this play differently:

2nd - 12:33 - 1st and 10 - terrible
Run to Beisel's gap. He moves up DIRECTLY behind DE (Thomas) rather than rushing his gap. Thomas is double teamed by OLG and OLT so Beisel is effectively blocked by the same guys blocking Thomas. After the intial double team of Thomas, the OLG slides thru and picks Beisel off of Thomas' back and blocks him outside and back completely away from the runner. Beisel ends up 5 yards from the LOS on his back. The runner makes 4 yards thru the OLG gap.

m: 1st and 10
r: Dive over LG, 4 yds
o: WR to each side, TE flanked to each side, TB.
d: 3-4, CBs soft;
DL LeKevin Smith, Sullivan, Santonio Thomas
LB Colvin, Gardner, Beisel, Banta-Cain
CB Samuel, Wilson
SS Sanders, FS Hawkins
b: Poor camera work as always - Sullivan doubled by RG/C goes down with the RG tripping the RTE; L.Smith drives the RT onto the pile in the middle; The C release off Sullivan and takes on Gardner upfield; Beisel met the LG in the hole and held his ground; S.Thomas stood up the LT/LG, then the LG released to Beisel; Banta-cain set the edge on the LTE; Hawkins blocked by LWR; Sanders met the RWR by the pile and drove him backwards onto the pile.
a: Gardner is credited for the tackle in the NFL.com play-by-play, but Beisel and S.Thomas drove their blockers back into the hole forcing the runner into Sullivan’s dog pile; Banta-Cain did a nice job of sealing the edge and forcing the play to stay inside.
You are technically correct, there was a run play heading for either the 'A' or 'B' gap to Beisel's side. Where I find your analysis unconvincing is your remark that "Thomas is double teamed by OLG and OLT so Beisel is effectively blocked by the same guys blocking Thomas." This presupposes Atlanta's offensive linemen are limited to one block per play.
A close look at our own offensive linemen indicates they frequently (as in some two or four players double and release or chip and release on almost every play run) double-team a DL long enough for one of them to gain control of him and steer him out of the play, while the second then releases to block a player at the next level (usually a LB). You will also see our offensive linemen initiate a block, then hand the player off to another blocker so they can block upfield. Put simply, an OL has blocking assignments, plural.
In this case you see Beisel being blocked by two guys assigned to block Santonio, and I see Santonio holding his ground against the double-team, then winning the battle when the LG release the double-team to block his 'second' assignment, the LB (Beisel).
Beisel's job on this play, assuming he is responsible for the left 'A' and 'B' gaps in a basic scheme, was to
control the LG to control the 'A' and 'B' gaps. Whether that was his actual responsibility in the game, I can't say but, his actions had the same effect as if that was indeed his responsibility. So what I saw was the NT partially lose containment on his gaps as he was knocked down by an initial double-team (note: one of those players who double-teamed Sullivan then went on to block Gardner - multiple assignments or 'I have nothing left to do on this job so I'll find another', your call.) - I say partially because Sulivan was not in a good position to make a play, but two 300 lb. road blocks on the ground will slow a RB. I saw Beisel move into the area where the run was going and be met by an offensive lineman releasing off a double-team:
1.
If the LG had stayed with his double-team Beisel would have met the RB head on in the hole.
2.
When the LG released his double-team to block Beisel the "defensive team" worked as a team with Beisel and Thomas controlling their blockers well enough to force the RB into Sullivan's tire drill, Beisel and Thomas succeeded because Banta-Cain controlled his man and forced the runner to committ inside or take a wide, time consuming swing to get outside. Once the runner got in that pile he could have tripped, or been grabbed by Gardner and/or Sullivan, and/or LeKevin Smith all piled up together with their blockers.
Gardner got the credit on NFL.com, but the three players who took on the left side of the line, made the play. Beisel was one of those players, you rate it a terrible, I rate it 'he successfully played his responsibilities within the scheme.'
I'll resume breakdowns tomorrow (God willing), maybe I'll see things more your way, maybe I won't, in the end, BB makes the decisions and I get to tell PATSNUTme "I am a Homer, DOH!"
