I'm not looking for bombastic commentary.... but the best kind of commentary I feel is where the commentators set off (at least at the beginning of the game) with a sense of optimism and hope... sort of like it's going to be a rocky journey tonight but we're in this together hoping for a greater good.
I also think that a prerequisite for a co-commentator is good communication skills, the ability to add some lightness to proceedings at times and a quick turn of phrase!
For what it's worth, if you look back to youtube RTE coverage of the Belgium '97 playoff defeat, it struck me after the game how Bill O' Herlihy and panel spoke highly of team in defeat.... however I think post Saipan especially, perhaps some realised that negativity makes more waves in Ireland than positivity.
I must say that I would have enjoyed watching the Poland match the other night a lot more (despite our struggles in Warsaw) and found it less of an ordeal if our state broadcaster had realised that on a Sunday night, the average man, woman and child could do without the moanfest before the week ahead!!!
