I've seen Cassel make huge strides this year from a mechanical standpoint, and he's just emrging.
To suggest he's reached his ceiling is ridiculous.
It's possible that he has, but highly unlikely, because it's well documented that he puts in the work to improve.
That being said, the thing that has me sold on Cassel right now is that we see a team that believes in him.
That's well over half the battle.
He grown into the clear leader of this team.
