Hey Pro,
nothing concrete I can tell you, just reading between the lines.
He had 75 Inside 50's, and only 56 Rebound 50's. From that we infer he had a lot of games more through the centre and wing, than deep in defence. Only 7 of his 21 games had more Rb50's than In50's. He had 4 games with more than 3 Clearances (rnds 1, 4, 5, 7) and they were for 6, 6, 9, and 9 Clearances respectively. You can assume he played mainly Mid those days. He had 5 games with 3 Clearances, which is more than your average non-Mid player ever gets, so we can assume he played a share of Mid those games (rnds 3, 6, 10, 22, 23).
I know it doesn't help too much, but without access to heat maps, it's hard to be completely sure, one way or the other.
