The artificial pitch was still new enough and every damn injury, including a turned ankle at an away game seemed to have the blame lay on the oriel pitch. Less that it was an injury risk and more that some players just didnt like it. Byrne was one of those iirc. A bit earlier, having Declan O'Brien on the books showed that not all players do the professional thing and play for those paying the wages rather than getting balled up in the local rivalry stuff.
It was a feature of Dundalk signings for ages that they were great...years before. Costello, Goeoghan, Doolin, Byrne, Hawkins, O'Brien, i'd even through Haylock in tbh.
