I think at the moment he is the best option, in the short term. Reading WP report about his performance at yea was encouraging. If he was simply getting outmarked at each contest I would be worried, but by ensuring the ball goes to ground if he doesnt mark it is a good thing, even if he doesnt mark it as often as you would hope.
On the weekend he took the best defender that allowed jack a bit of leeway, and if the opposition put the best defender on jack it will probably free up Poly to take a few grabs. Naturally the sides with the best defence in the league are going to hurt us either way, but that was always going to be the case this year.
If poly can keep doing what he did at yea it takes the pressure off rushing grithiths and astbury. Already many people put these two in their best side, yet grithiths has not even played a game, last I heard he isnt even in full training, recovering from a shoulder injury. The same with Astbury, only played one NAB game and showed signs, but that's it. If both of these guys make it we will be lucky, but they are a long off being part of a match winning forward line.
To be able to wait until they are ready to play is a good thing, even if it that means we don't see much of them in Richmond colors this year.
