Too many.

Bernard Jackman has made an interesting observation regarding Leinster Rugby and their current dilemma that could be detrimental to both them and Irish Rugby as a whole.

As things stand, the eastern province will have four out-halves at their disposal next season in Ross Byrne, Harry Byrne, Sam Prendergast, and Ciaran Frawley.

There has been talk of Prendergast going to Connacht next season on loan, with JJ Hanrahan suffering a serious injury that will keep him out for much of next season, but it now appears the youngster will be staying put.

And as far as Jackman is concerned – one of them simply has to go.

“It is a Leinster issue and an Irish rugby issue in terms of depth chart at 10,” Jackman told Against the Head

“Next year we are probably down one because Billy Burns is going to Munster presumably as a back-up.

“Connacht have JJ Hanrahan injured; at the moment they have one 10: Jack Carty.

“Ulster brought in a young 10 from New Zealand who is Irish-qualified, maybe he will be the difference.

“Joey Carbery is going to Bordeuax so he is no longer eligibile for Ireland.

“In a position where we were a little bit light this year – theoretically we are going to be lighter next year.

“Sam Prendergast is a talent; he needs to play. I am not saying he needs to go to Connacht or Leinster – he needs to play somewhere.”

Jackman believes it will be very difficult for any of the Leinster 10s to develop with four on the books and believes one has to go.

“What is best for Ireland is that Sam Prendergast plays. What is best for either Connacht or Leinster is he plays. Not all the time, but he needs to play more than he has so far,” Jackman added.

“Leinster with four 10s: Ross Byrne, Harry Byrne, Ciaran Frawley and Sam Prendergast; it is very difficult for any of them to develop to the level they are going to have to.

“I would say yes. One of them has to leave and that is a decision for Leinster.”
