Stick to what you do best Jack - scrummaging, tackling, clearing out rucks, pinching turnovers, etc.
Leinster survived a furious Glasgow Warriors comeback
and two floodlight failures to win their final home game of the regular PRO12 season.
Having comfortably led at the break, Leinster fell 30-28 behind only for Joey Carbery's penalty to secure the home win.
After a wait of almost 15 minutes on the pitch for both sets of players, after the lights went out, Leinster needed to repel Glasgow's advances in the final 90 seconds before they secured turnover ball.
Jack McGrath plucked the ball up and set off away from the ruck. The loose-head prop then made an attempt to kick the ball out of play and end the tie.
He almost made a complete hash of it but, luckily, Adam Byrne was there to carry the pill out as a Glasgow winger chased it down.

Let's hope Warren Gatland and the rest of the British & Irish Lions coaching staff didn't see that.
Looks like a prop. Walks like a prop. Kicks like a... prop.
