The 1st play was legal. Kyle wasn't engaged with another blocker, he was free. The Pats were doing that a lot to him the first go round also. I hate those blocks, I'm sure he does too. But it is legal. (Though there have been talks about making those cut blocks illegal)
I should add, it becomes an illegal block when the blocker rolls at the legs.
I don't remember seeing the other tho.
