Yeah, me too. I actually gave my analysis in a comment there with a timeline, the numbers with * are ref mistakes I deemed obvious.
1 - 0:05 you can see the Red 4 on his feet with his hands on the ball, the yellow player not releasing the ball
2 - 0:13 2 yellow players off their feet handling the ball
3 - 0:19 obstruction, you can see it how at 0:21, yellow player stops just in time to cover the ball carrier
4 - 0:34 the neckgrab that should have been a yellow wasn't penalized...
*5 - 1:50 not visible in the footage, the ref signaled offside at scrum (i'm gonna let this slip as a ref mistake)
6 - 2:00 yellow players are offside at maul, it's difficult to know which team is carrying then a yellow #2 contests the ruck from the red side
7 - 2:15 forward pass not a penalty. It's difficult to say from the footage, i'm goinna let this slip as well
*8 - 2:52 seems unclear at first, after watching the full scene it looks indeed like Belgium was given a penalty here out of nothing.
9 - 3:00 was this supposed to make us believe Spain deserved a penalty for a late tackle? Red was already commited, no argument.
10 - 3:11 fair drive by red followed by a side entry by yellow. Red player righfully slaps his left cheek at 3:15
11 - 3:26 #7 yellow clearly not rolling away
12 - 3:36 Red clearly on his feet contesting the ball, a case can be made if 7 red actually rolled away in time but the ball was out there
13 - 3:49 you have to look for the actual footage here, spain collapse the maul
14 - 4:05 ...just look at it...
*15 - 4:22 Wrogful penalty awarded to Belgium, admitently was a red boot in the scrum, ref probably thought it was a yellow hand in there
16 - 4:32 Dead ball - scrum. No argument
17 - 4:45 wheeling the scrum, you can see how Belgium was stable while Spain tried to dance around.
18 - 5:12 this was a penalty for Spain, but it was stopped for an apparent knock on made by Spain (not seen but presumed) Belgium players stopped playing.
19 - 5:40 you can see Red with on his feet with hands on the ball
20 - 5:51 clearly from the side, no discussion.
21 - 6:12 it's difficult to see, but the infringement seems to be a yellow player playing the ball on the ground. The card was probably given for repeated infringements in the ruck (which we've seen)
22 - 6:40 throw not straigh - scrum
23 - 6:49 In the scrum that followed Spanish 1st row raised, Belgium played advantage, it's arguable if the pass at 7:09 was forward, they knock it on and then return to the original scrum penalty
24 - 7:36 the ref wanted to let it go away, but look at his gesture. One spanish player actually covers the mouth of his teammate to prevent him talking ****...
25 - 7:47 maul not contested, but can be argued that Belgium players made contact with the ball carrier. Either way, the maul must be called out by the ref.
*26 - 8:08 Indeed not seen by the ref
27 - 8:25 Red had his hands on the ball. What is the argument?
28 - 8:48 Yellow #3 clearly lost his footing in the scrum. No argument.
*29 - 9:00 It looks like a high tacke, even though not clear, I'm gonna let this slide
30 - 9:34 He's holding the ball because the tackle was not complete, you can see the tackler not rolling away either because he's still in motion. Arguable, but I think the ref was right on this one.
31 - 9:41 The penalty was given, but usually no cards are given for deliberate knock ons... it was not a scoring situation and it's not clear that an attempt to catch the ball was not made.
32 - if you can pause at 10:03 you can see 11 red being blocked from tackling the yellow player. Accidental obstruction - penalty.
