I'm not sure how exactly we could have ensured we got Grigg, without doing this trade?
I am assuming he improves our list over Collins.
Which means what?
I read it as meaning Hardwick wants heavier bigger bodied players, where as Wallace wanted outside quick runners. And he is willing to do 1 for 1 trades of equally ranked players to get this heavier bigger list that can play his style of game.
Its back to the Frawley era. Hopefully these bigger players will be able to kick (Grigg ain't known for his kicking) unlike in the Frawley era and hopefully we keep to the game plan for more than 5 minutes into the game unlike the Frawley era.
All in all it seems to be a positive for me, getting a player who is more likely to be able stand up in the tackle and still dish off a pass. The modern game is almost constant tackle ball, so players like Grigg should have an advantage of players like Collins.
