4-down Friday is back. Here is a look at four things to keep an eye on in Yale’s season opener against Lehigh at 1 p.m. on Saturday at the Bowl.

Under center: Morgan Roberts will be the starting quarterback when the Bulldogs open their season on Saturday. The talk is that Roberts is much improved and really made strides in the offseason. The offense around him is healthy and talented. Roberts will get his chance Saturday to prove he was worthy of the hype.

A healthy Varga: There were questions during preseason if standout running back Tyler Varga would even be ready for Yale’s opener because of a foot injury. The Bulldogs breathed a sigh of relief when Varga came back to New Haven for camp and looked like his old self. Varga was held out of the Brown preseason scrimmage as a precaution. He’s a tough, physical runner, so it will be interesting to see how he holds up in his first game back.

Kicking game: Yale struggled with its kicking accuracy during the preseason. This will be critical, as Yale can’t afford to leave points like this on the field. Kyle Cazzetta won the battle for field goal duties.

Young defense: With seven freshmen on the two-deep defense, the Bulldogs are young. They will certainly be challenged in week one against a battle-tested Lehigh team that loves to run the ball.
