That's both correct and incorrect.
I watched the game and Clayton only threw one passing TD. I'm sure that will be changed.
As far as the scoring, that's correct. The way the scoring works (blame FBJoe, not me

) is that Clayton will receive 6 points for his passing TD as scored under Total TDs. But since passing TDs are supposed to be scored as 4 points, all passing TDs are scored as -2 so everything evens out.
Clayton got a throwing TD and a receiving TD.
So he gets 12 points for 2 Total TDs and -2 points for a passing TD. 10 points as intended.
