Never heard anyone refer to him as anything other than Gumby and, honestly, **** what Committi says anyway.
There is no doubting Gumby has not played at the required level but what most do is make the observation and write him off out of frustration. Like I said above, he would have been nothing short of dominant against West Coast at the Dome in August had he not brought his butter fingers. These sorts of errors, though, are psychological which I'd bet are related to the knowledge that he was playing for his career at Essendon. He's routinely been able to take these sorts of marks.
He still got the ball 11 times and had two shots on goal. Say that he doesn't drop the marks, or his leads are honoured because you guys have a functioning forward system, that is almost 20 time he will have the ball as part of a chain of possession that results in a forward 50 entry (based on the nature of where he get his footy). When you break it down there isn't really that much more that he has to do to be a good contributor.
It will be interesting to see how much more he can be developed physically.
