I don't disagree with the top 3, but my order would be
1. Prestia
2. Houli
3. Stewart
I guess people are going to think I am trying to be cute not nominating Stewart as No.1 but my reasoning is below.
The impact that Prestia had on us winning the three flags is immense. If we don't get him, we don't win them, pure and simple! I truly believe this. He didn't do it singlehandedly, but his efforts delivered on the belief of Peggy and the board that we were on the right track, and showed us the way for ensuring we don't return to the 'Lost Years". His recruitment was an absoloute masterstroke. Easily the best use of a Pick No.6 in AFL history
Houli has been a great player, not in the league of Prestia or Stewart, but great nonetheless. But his impact on our club culture has, I believe, set us up for a much brighter future than any other player I can remember. There is true resilience in diversity, and I personally believe that Bachar has driven both a massive injection of diversity, but also assimilation, into our club. He is off-field leadership has enabled the club to adapt and respond to many issues that other clubs have failed to deal with effectively.
Stewart won a Brownlow, which is why no doubt he got the number one gong. Anytime you can recruit a Brownlow medalist and he wins another at your club, you are talking a serious footballer. He was the best footballer of the three no doubt, and has been recognised by both Richmond and St Kilda (in the Team of the Century at both clubs), and AFL Hall of Famer and AFL Legend. But he did join a team that was already full of champions, and though the case might be made that he was very influential in us winning the 1973 flag, I don't think it is clear cut that we don't win that flag if he didn't play. I could be a very harsh judge on this, but I am not sure he had the impact on either our culture or off-field success that the other two had.
