Every time I've watched Arrow he's done plenty of passing in the lead up to sweeping plays, playing similarly to someone like Gallen, if I was going to compare it to someone in the NRL, he's no James Graham, but he can definitely pass the ball accurately and in a timely fashion.
And those off-load statistics 100% back-up what I was saying, in comparison to McGuire he's absolute light years ahead of him if we're looking for a lock similar to Corey Parker that can offload and defend at a high rate.
Also, in regards to your stats, you said that his number of offloads were "no where near that number" in the ISC, but followed up by saying he played in 12 NRL games, would I be correct in saying he played far fewer games in the ISC in 2016 than he did in the NYC in 2015? Statistically speaking he probably averaged more offloads per game in the ISC than the NYC.
And just as a side note:
McGuire in 2016: 24 games, 16 offloads.
