Quote Grimmy="Grimmy"Gelling scores plenty tries and makes nearly 100m a game. Plus he's the better defender of the two. I'm not saying he will win us the game, but I'd rather have a player out there who makes a couple of handling errors, but also takes pressure off the forwards, scores when put in space, and is solid in defence, than one who is fairly anonymous in attack and suspect in defence. That sums it up for me, Gelling drops a couple but at least he gets involved and does a lot of positive things too.'"
Gelling averages around 11 more metres per game than Thornley. It's not a massive difference; it's the equivalent of about 2 carries (and Gelling averages 2 more carries per game than Thornley).
Gelling scores more than Thornley (0.8 tries per game compared to 0.6) but that is surely offset by the fact that Thornley is 5 times as likely to make a try assist. Thornley averages a try assist every other game whereas Gelling averages a try assists every 9 games.
Gelling is twice as likely to make an offload and more likely to break a tackle but Thornley averages over twice as many clean breaks. Gelling is nearly 3 times more likely to make an error, 3 times more likely to concede a penalty while they both average around 1 missed tackle per game.
There's not a vast difference between them except for when it comes to try assists, errors, penalties and clean breaks.
