CommBank Stadium: The records kept tumbling for Penrith as they made light work of yet another alleged premiership threat in Melbourne. Good Friday became a great Friday for the Panthers as they thumped the Storm 50-10. In doing so, the title favourites became the first team to start the season with five-straight triumphs by 20 points or more. Balmain (1985) and Manly (1995) could only do it four times in 1985 and 1995, respectively. It was Penrith’s biggest-ever win over the Storm. It was Melbourne’s biggest defeat since the famous 40-0 grand-final blowout against Manly in 2008. And winger Tom Jenkins became the first winger in history to start the year with five straight try-scoring doubles. He brought up the double with three minutes remaining. The only other player who came close, Billy Slater, who was sitting in the Nine commentary box at CommBank Stadium, scored four doubles, and only scored the one try in round five back in 2012. Seriously, who is going to come close to this lot?…
