First off, Houston should have been called for holding or illegal blocks in the back on BOTH the long returns. I am not surprised they weren't because the refs didn't call but one holding call on Houston all night..
On the first kick-off, (94 yard return) You had, from left to right:
Arrington, Bolden, Rivera, Ebner, White, Gostkowski, Slater, Koutivedes, McCourty, Wilson, Cole.
Bolden and Rivera both got blocked out.
Cole and Wilson ran too deep in their lanes and blocked themselves out.
Ebner got held by the guy he engaged.
Koutivedes seems to be the one who lost his lane assignment as, he seemed to be the one who Manning ran by. Slater might have also been out of position slightly.
On the 4th return, where Gost was called for the horse-collar, you had the following from left to right:
McCourty, Cole, Wilson, Koutivedes, Slater, Gostkowski, White, Ebner, Rivera, Bolden, Arrington.
On this one, Cole and Bolden are both held, allowing Manning to get by easily. However, Arrington also seemed to be out of his lane.
On the 65 yard return, from left to right, you had:
Arrington, Bolden, Cole, White, Slater, Gostkowski, Ebner, Koutivedes, Rivera, Wilson, McCourty
On this coverage, White and Slater switch lanes just prior to engaging. However, White goes down and effectively cuts off Rivera and Koutivedes from the play since they are right on top of him.
Ebner was illegally blocked in the back, knocking him down. This forces Slater to JUMP Ebner in an attempt to stay in the play. This is after Slater was also pushed from behind.
Cole seems to be out of his lane and is too close to Slater, not giving himself enough room to cut back towards Manning and this allows Manning to run by him.
Bolden didn't adjust at all on this play and over-ran it and took himself out. I was surprised that he stayed so far to the left despite the ball being kicked towards the opposite side of the field. I would have expected him to cut back behind Cole and Slater to help Arrington with contain.
There was ONE kick coverage that was done perfectly. The one that held Manning to just a 10 yard (or so) return. It was the same as the previous set-up, except that White and Slater swapped places to start and Ebner and Koutivedes swapped lanes just before hitting the blockers of Houston.
