Tom Farrell for Ireland?

Just making this post to ponder on a possible replacement for Robbie Henshaw in the future, considering he's looked a little off the last couple games, not to say he can't come back in form or deserves to be pushed out of the squad but still good to look at alternatives.

I think Tom Farrells been exceptional for Munster recently, only downside being he's the same age as Henshaw but with much less experience at very high level rugby.
