I'm not sure that his tackling figures are that high actually, your other stats look fairly accurate but
Using stats from TZ:
Code:
Round Disposals Marks Tackles
14 27 6 ?0
15 28 9 3
16 32 4 ?0
17 23 6 2
TZ sometimes omits tackles for every player but given that in round 14 even 1 tackle was listed against the player stat for other players and in round 16 players with 4 or more tackles were indicated.
To average 5 tackles in 4 weeks means he made 20 tackles in that time.
Given that we know for sure he made 5 tackles in two weeks in the other two weeks he had to average 7.5 tackles per week - I find it highly unlikely that the stats men decided to overlook those sort of tackling figures. In fact my info is that tackling and defensive pressure is what he needs to work on. The figures seem to support my statement.
