Evra's greatest attribute over Irwin was his fantastic ball-carrying ability. He'd get us up the pitch in seconds and do it regularly with great energy. The opportunities he created for himself were often wasted though, sadly. Bad crosses were quite normal. But he was very fun to watch, a wonderful player.
Ultimately though, you'd get more out of Irwin's attack, even if he did it 50% less than Evra, because his accuracy was much more dependable. He wasn't one for lung-bursting runs like Pat, but he did time his runs to perfection most of the time. Even now, in legends matches he arrives at the right time to help the winger and his delivery is nearly always great. Super dependable with terrific technique.
