I think you're missing point lad.
If you're honest, POM/TOD wouldn't have got the game time he has this year if Wallace and Leamy were not injured.
Take Nagle for example, has only featured in 7 games in the Rabo this season (5 starts), meanwhile, Micko is clogging up the system contributing nothing particular special other than honest effort. Do we have to wait till he's 27 to make cement his place like DRyan? Meanwhile, Mark Flanagan for example has figured on 5 games this season and he's a year younger.
There's guys like Will Chambers and Save Tokula being brought in who are complete muck and they are blocking development of guys like Luke O'Dea or Ivan Dineen.
The (mis)management of the development of Keatley and Cusack has been nothing sort of lamentable. If Hagan coming back to Leinster was a bad move for his development, then the move to Munster has been nothing short of catastrophic for Keatley. 2 substitute appearances for the chap. Contrast with Madigan....
What are guys like Tom Gleeson, Denis Hurley, Niall Ronan bringing to the table....not a whole pile I'd say. They aren't good enough and frankly they aren't going to get a whole pile better. Like Gleeson is 27 this year....It's not gonna happen for him.
Put the young guys in there. Leinster have, Ulster have, Connacht are doing it. It's just not happening quick enough in Munster and it's because the management would rather take punts on the likes of Peter Borlase or Willy Chambers or whoever.
BTW, winning a game by 7 points after extra time is hardly ripping anyone a new one.....
Ok, I'll address the players you mention:
POM was selected on merit and has been mapped for a long time.
You are correct that TOD probably would not have been selected in the HEC but for Ronan's injury, which is fair given that Ronan was in better form (the best he's shown for Munster in fact and a bit of a revelation this year).
Nagle has had a few injuries and still lacks bulk. Our depth at lock is making it difficult for him and he's lost out a bit to Dave Foley but that's life. MOD is retiring.
Btw, can you honestly claim Flanagan would have gotten so many games if Leinster didn't have injuries? You didn't take long to sign a stop-gap and he's now back in the A team (and Toner's sitting on the bench behind a 37 year-old Kiwi).
Chambers and Tokula are 13s. O'Dea's an out-and-out winger and Dineen has been injured most of the season. The one young player to be potentially blocked by them was Barnes but he actually got loads of Pro12 games this season and a couple of HEC starts too.
Cusack is a very ordinary player and has not been worthy of much game time - have you honestly even seen him play?
Keatley has had as many Pro12 starts as Madigan this season (13) but has simply failed to deliver consistently (I really wish he had). He may regret his decision to come to Munster but he can't say he wasn't given opportunities. Madigan has grabbed his with both hands. That's the difference.
Tom Gleeson has lost his place in the pecking order to a younger, better player (the aforementioned Barnes). I doubt he'll get a new contract.
Denis Hurley has lost out to a younger player (Jones) but is a very decent HEC level 15 and worth his place in the squad.
Munster blooded Archer, POM, TOD, Murray, Barnes, Zebo and Jones in the HEC this season. 6 of the 7 started at least one HEC game and 5 started the QF. Sherry also got his first start in the HEC this season in a QF.
When you say "put the young guys in there", how many more would you suggest?
We're all red on the inside.
