North Melbourne coach Brad Scott says despite some injury concerns in JLT 2, the club remained cautious ahead of Round 1.

Halfback flanker Marley Williams had a tight calf in the first quarter and missed the rest of the game, while defender Sam Wright couldn't take a trick, experiencing quad tightness in the last term after copping a big hit from Power forward Todd Marshall earlier in the game.

"Marley just tightened up a bit in his calf, a bit of a spongy surface out there, so he just felt a little bit tight," Kangaroos coach Brad Scott said.

"We're optimistic he'll be okay.

"We've had a few, so we're overly cautious for a reason.

"We'll get Wrighty assessed as well. He had a hamburger with the lot today, he had a few things going on."

The game turned into a shootout, with the new set starting position rules having a significant impact in 35 goals being kicked.

"It will make the game better," Scott said.

"Not necessarily easier to coach, it will be really hard to stop when teams are really dominant, but so it should be.

"The game was too easy to shutdown at times with the rules the way they were.

"Even if it's successful, it's not necessarily the best look for the game.

"The changes are significant."
