Worpel had another good game, but you've put 3 players that had the same or more clearances and more contested ball than he did in your 'poor' category (Shiels, Mitchell and JOM). He also had 7 clangers (2 more than the worst of your 3 'poor' mids, with Mitchell having 5, JOM having 2, and Shiels only 1), and went at 51% efficiency. 7 clangers was the most on the ground. There is a lot to get excited about with Worpel, but IMO this was the first of his recent batch of games that showed some of the defects in his game that let him slip to pick 45.
if you base your understanding of a game on stats rather than actually watching a game, you'll be fooled more often than enlightened...
