Saurus warriors may not kill many knights a turn, but the enemy will run out of knights before you run out of saurus. as soon as you have him in CC, he wont go anywhere (unless it is fleeing with you chasing after, lol)
MoK Knights. 6 of them. 19 Attacks. ~13 hits, ~9 wounds, ~8 dead Saurus.
12 Horse attacks, ~(presuming WS3, becuase I can't remember their WS) 6 hits, 3 wounds 2 more dead Saurus.
That's already 10 dead Saurus. Now, in a unit of 30 (because that seems the norm, with spears)
Sure they kill 1 (24 As, 12 hits, 6 wounds,1 dead)
But that only dros the death toll by ~1 Saurus so you'll actually be out of Saurus really quickly.
Heaven forbid they have MoN and the Banner of Rage, then you'd only kill an astounding 0 (well, like, 0.6 re-occuring chance, but still).
Saurus tarpits really don't work against 'real' chaos knights.
