You say this, But the storm have spent $3 mil on 3 players for basically ever... The cap will be higher than ever before so spending $3 mil on 3 of the 4 spine members (1,6,7,9) will become pretty common. I mean Broncos are going to possibly be spending that much on Boyd, Milford and Bird as well. Cowboys would be close with JT, Lolo, Morgan, Dragons (already spoken about), Storm (if they get a Foran like player) with Smith and Slater, Bulldogs with possibly Woods, Tedesco and Mbye, or Rooster with Tedesco, Pearce and Friend.
I think basically every club will end up spending around the 3-3.5 mil mark on 4 players.
