My definition would be the 22 in the best form who give us the best chance of winning the game. And right now, that includes Dangerfield. I've seen nothing in his performances this season that has ever given me cause to doubt his commitment. Whether he's staying or going, it's pretty obvious that right now the number 1 thing on his mind is winning finals and, hopefully, a premiership this year, not where he may or may not be playing next year.
As for the Tippett comparison - it's pretty unlikely we're going to run into Geelong during this finals series, so it's not really a valid point. And even if we did, I still think you pick the 22 players based on how they've been performing in recent matches, not how you think they MIGHT perform in the next match. If it was round 23 and we were out of contention, maybe. But right now we are up to our eyeballs in this thing, and we should be picking our team with an eye on winning finals right now, not on list management issues which can wait for the end of the year.
