Robshaw is constantly near the breakdown, is opposite or near the first opposition receiver, ergo his tackle stats are high, but doesn't mean he's sending them backwards. Same in attack, he's near our first receiver or is first receiver so he takes the ball and makes a carry, but these carries aren't making hard yards.
Robshaw is reliable, but we have enough people in the team who can do that. Tackle well, carry for half a meter. We need someone stronger and more aggressive at 6, or someone more dynamic.
