Last week, we examined a few advanced statistics where the Buffalo Bills have seen a marked difference since last season -- good or bad.

With another game to broaden the sample size, let's give those numbers a refresh, concluding with the special teams:

Stat: Average distance from goal after opponent punt return

2013: 70.0 yards (27th)

2014, through Week 1: 85.0 yards (fourth)

2014, through Week 2: 84.2 yards (second)

Analysis: Colton Schmidt's two strong weeks of punting are second only to his former team, the San Francisco 49ers, who cut the first-year punter in August. The Bills lead the NFL with 77.8 percent of their punts returned from inside the 20-yard line, while they rank third with 33.3 percent of punts landing inside the 10-yard line. There have been zero touchbacks through two weeks. Through two weeks last season, Shawn Powell had 33.3 percent of his punts land inside the 20-yard line and 8.3 percent inside the 10-yard line.

Stat: Average distance from goal after opponent kick return

2013: 76.8 (16th)

2014, through Week 1: 81.2 (7th)

2014, through Week 2: 80.1 (9th)

Analysis: Jordan Gay kicked off eight times Sunday, tied with the Washington Redskins for the most in the NFL. Five of those kickoffs went for touchbacks, a 62.5-percent rate that ranked 15th in Week 2. Gay's touchback rate for the season is 71.4 percent -- tied for seventh-best -- which is a significant improvement over the Bills' 41-percent rate last season. The Bills' decision to carry a kickoff specialist has paid off early.
