It was another compelling weekend Jon Ryan Youth Jersey of World Cup action, with Scotland and Samoa serving up a thriller, but my favourite matches over the weekend were the two battles to finish top of their pools Wales against Australia and Ireland versus France were ferocious, savage games. They were brutal and gladiatorial and you could feel how much was on the line for all four teams - coming second wasn't an option and it was great to watch. The mighty Irish Ireland beat France to reach the quarter-finals, and they were unbelievably brilliant in the second half. They won despite losing Johnny Sexton, Paul O'Connell and Peter O'Mahony, and it shows how much belief head coach Joe Schmidt has instilled in this team that they can go on and deliver without those leaders on the pitch. Sean O'Brien summed it up in his post-match interview when he said, and I'm paraphrasing here, "it was sad that the lads got injured but the games keep coming and we have to get on with it". They dealt with it, the other players Arik Armstead Womens Jersey stepped up and they got on with it. Ian Madigan, who came on at fly-half for the Irish, has a very different game in his head to that of Sexton because of their different skill sets. Sexton is very experienced and seems to like detail and organisation - he does not like to play off the cuff too much - whereas I don't think Madigan is a process player, he is more instinctive. However, one similarity would be their goal-kicking, because at provincial level Madigan had an 87% kicking success rate for Leinster last season, which is top class. Madigan might be more instinctive in his approach but has the skill set to implement a Schmidt playbook, because otherwise I don't think the coach would have him in the squad. If Sexton doesn't play against Argentina, Madigan will have to temper his urge to run with the ball and make sure he executes the kicking strategies accurately, which will take a lot of concentration. You simply can't replace players like O'Connell and Sexton like-for-like because of how much they are involved in running the team on the field - a different voice just won't be the same. The replacements have to play as big http://www.nflchargersofficial.com/SUPER-BOWL-MELVIN-GORDON-JERSEY as the O'Connells and Sextons so at least the practical element to the team performance isn't missed. Lock Iain Henderson is playing some superb rugby so his impact will be positive, and after Madigan came on and played so well he, Schmidt and the team will be confident he can raise his game again. O'Brien will be missed if he's banned for the incident with Pascal Pape. He's such a destructive runner, there's no one in the Irish back row that will have a similar impact. Someone can replace him and achieve as many turnovers, but he'll definitely be missed in attack when it comes to carrying the ball. Ireland's quarter-final opponents, Argentina, have been very good, going about their business to great effect. Their opening game against New Zealand was fantastic.
