Since he is such a hot topic at the minute, here is my 2 cents about Tyson:
He has 2 major problems, he is slow and he is a terrible kick.
Now the latter is the lesser of the problems, for a midfielder at least, we can probably deal with 60% efficiency by foot if he can keep his hands up around 80-85%. Judd and Swan are both brownlow medal proof that you dont have to be a glorious kick to be a star midfielder as long as you can get your hands on the footy and give it to someone who is. we'll all love tyson forever if he gets the ball in and under and hands it out to le like of salem running past who has the skill to hit someone lace out.
The bigger problem I see is he is slow moving the ball on, he gets caught holding the ball more than any other player in the competition, and this is harder to fix. People calling for him to be dropped but I feel he will dominate in the VFL simply due to the extra time he has. IMO we have to persist with him at AFL level and he has to get better at moving the ball on quicker. Going down a level and playing exactly the same might help his confidence but wont change the fact he will continue to get caught at the top level. I'm open to sugestions as to how the VFL could improve this skill but right now i just cant see it helping
