Winning the Grand Final is all about peaking at the right end of the season. How many times have we seen teams dominate all year (Storm!?) only to fall short to a team hitting form when it counts most?
The 2009 season is especially famous for this. The Dragons, Bulldogs and to a lesser extent the Titans, were far and away the best teams across the regular rounds.
The Storm, in fourth, finished five points behind the table-topping Dragons and Broncos. The eighth-placed Eels were four points further back.
Both found form at the right end of the season and would meet in one of the most famous, and now infamous, Grand Finals of the modern era.
Obviously, both teams contesting this Sunday's Grand Final are in form. Two straight wins is the minimum requirement, but not every player is currently firing on all cylinders.
We look below at the five form players heading into the decider. These aren't necessarily the best players, but the players who enter in red, hot form and will likely decide the premiership.
Let us know below who you believe is entering the Grand Final as the form player of the competition.
4. Isaah Yeo
Isaah Yeo is the kind of player you can watch for 80 minutes, see him 50+ times and yet is barely registered. He just goes about his work as one of the top three No.13s in the game.
Across three finals games he has made 127 tackles and missed two. He's also averaging almost 135 metres per game against the Bunnies, Eels and Storm, who boast three pretty decent forward packs.
Yeo simply does his job. Across the opening three weeks of the finals series he has completed said job to near perfection.
His one-on-one battle with Cam Murray is so crucial this Sunday. Two in-form megastar locks colliding with the game's biggest prize on the line. Sign me up!
Yeo played all but three minutes of this year's finals series and has been in the top-five forwards this year. He won't attract the attention of the likes of Murray or Kikau but is equally as important.
