The full-back who headed the tandem was a notable line-bucker, although his weight was but 172 pounds.

The left tackle, Balcom, tipped the scales at 187, while the third member of the trio was twenty pounds lighter.

Together they represented 525 pounds.
Opposed to them were Gillam and Mason, whose combined weight was 312 pounds.

Gillam stood between left-guard and tackle, with Mason, his hands on the other's shoulders, close behind.
The Robinson quarter stared for an instant with interest at the opposing formation, and the full-back, crouched forward ready to plunge across the little space that divided him from the opponents' territory, looked uneasy.

Then the quarter stooped behind the big center.
"_Signal!_" he called.
