Best Defence in the CFL?

Look which team has only given up 372 points after sixteen games, the best in the league. That's right the Hamilton Tiger Cats. The Cats are fourth in offence with 436 points scored. I will also point out that the Argos are dead last in points scored with only 313. Bizarrely the Argos have given up 401 points yet still have a 500 record at 8 and 8.

I've noted in the past that the CFL is the ultimate home field advantage league. Currently the only team with a winning away record is Calgary at 5 and 3.
