When ROB first came to the Crows I mention his biggest weakness was his ground ball and follow up, in the years that I have watched him he has made those weaknesses his strengths in the SANFL,
At this time he is quicker and has a higher leap than Jacobs, add to his ground ball work and the only issue we need to see is how well he reads the play, if he has that game, I would say he is very close to Jacobs 2017 form.
You need to watch this Kid, when he was fit he was the Best SANFL ruck going around by a long shot if he did not do his Shoulder last year he would have played AFL.
Here is something to ponder, When you look closely there a lot of Clarke in Jacobs tap work I see the same in ROB.
Like I said he may or may not be as we know some ruckman take a long time to develop like Goldstein and Mumford even Ryder he wasn't really a ruck at the bombers. You never say never or he could be a plodder like Hudson and biglands were and serviceable at best.
I actually think Sauce will struggle to recapture his mojo and ROB will play if he cant bring it though, it could mean a long year for the crows
