Here is a look at four things to keep an eye on in Saturday when Yale hosts Army to celebrate the 100^th anniversary of the Yale Bowl.

Encore performance: Yale proved its offense is loaded, exploding for 683 yards of total offense in last week’s win over Lehigh. Morgan Roberts and company will need to light up the scoreboard once again if they are going to have a shot to upset the Black Knights.

Breakout watch: Keep an eye on wide receiver Grant Wallace. He had a solid game last week, finishing with seven catches for 67 yards. He also had a touchdown called back on a pass interference call. Roberts spoke very highly of Wallace coming into the season and the two had a clear connection in the spring and during preseason camp. Watch out for a breakout game for Wallace.

Contain the run: Army will use its triple option and run, run and run some more. That’s no secret. Yale’s young defense will need to find a way to maintain the line of scrimmage and try to force Army to throw some. The Black Knights attempted just five passes against Wake Forest last week. 

Festivities: The Army-Yale meeting is more than just a football game. Who knows when these rivals will ever meet again. Along with a free concert featuring both school bands at Woolsey Hall on Friday night, 1,000 cadets will march to Yale Bowl and paratroopers will drop in from helicopters with game balls. The halftime show will likely be the best of the season. So enjoy it all, Yale fans.
