i dont think so. Hoffman did get obstructed at the time, but Marshall still had a heap of distance to get to the line and Hoffman had more than enough time to plug the gap. He chose to pitch his tent just in front of the try line rather than move further in field. The fox sport team were all unanimous that was the wrong call but they were divided on the other one. Guess if we cant agree, how is the bunker supposed to keep everyone happy.
Honestly, that's rubbish. He was disadvantaged by not being allowed to move up in a unified defensive line with Robson, Benji ran into the space created by that (on Robson's inside shoulder), it was obstruction. He had time to get across the field, but not to get up and plug the gap - therefore was forced to make a much harder tackle (1 on 1 close to the line) than he would have otherwise.
Were the Fox team really unanimous? Jimmy Smith (on the right) seemed to be disagreeing as much as he could without Gaz (the least objective person - and perhaps worst game analyst - on the Fox Sports team) throwing a moody and walking off set.
Honestly... Gaz was also whinging about the other one - and his argument was that it shouldn't be Matthews' responsibility as the lead runner to avoid running into the defender. He might be a former player, but he clearly doesn't understand the obstruction laws at all - his opinion on these calls carries no weight.
It's an easy one to fix: if you're a lead runner, run at the gap not the player. Simple solution, and this all becomes moot.

edit: I see Archer came out with his public evaluation of bad decisions and said there was an error made by the bunker - in the Raiders/Panthers game, but not ours. Incidentally, it was for a wall in front of the field goal kicker - remember when we did that last year? It was legal then, but they produced a new rule against it before the start of this season.
