No, he did not.

Cappa - 73.4 overall (69.6 pass block, 71.2 run block)
Spain - 72.3 overall (58.9 pass block, 76.3 run block)

What doesn't make sense to me though is why Spain isn't even lower.
He's over 10 pts lower than Cappa in pass block rating.
Cappa had 792 pass block snaps compared to Spain's 611 pass block snaps.
Both allowed 5 sacks.
Cappa had 386 run block snaps compared to Spain's 384.
Spain had 4 penalties to Cappa's 1.

If you take Cappa's pass block rating multiplied by number of PB snaps added to the run block rating multiplied by the number of RB snaps, and then divide that by the total number of snaps, Cappa's rating would come out to be 70.124.
((69.6x792)+(71.2x386)) / (792+386) = 70.124

If you do the same for Spain, his rating would come out to be 65.615.

I know that the cumulative rating is not calculated like that, but unfortunately I don't know how it is exactly calculated.
I don't believe I've ever seen an official formula.
