• Michigan ranks fifth in the nation in total defense at 247.6 yards allowed per game. The 159 yards allowed against Wisconsin represents the Wolverines' season-best performance this season and second straight week holding their opponent below 200. Penn State finished with 191 total yards. The Wolverines allowed a season-high 331 yards in a 51-14 Week 2 win against Central Florida, while Colorado had 325 and Hawaii 232. Boston College is first in the nation in total defense at 202.0 yards per game, Florida is second (230.4), Ohio State third (237.8) and Kansas State fourth (239.8).
• Michigan is second in the country in passing yards allowed per game at 135.4, trailing only Boston College (124.0). The Wolverines, who played the first three games without Lewis, an All-American last season, have held opponents to less than 200 yards passing four times in five games. Saturday's win over Wisconsin was the second time Michigan allowed fewer than 100 yards passing this season, to go with the 56 yards Central Florida had through the air.
• Michigan ranks No. 1 in the nation in third down defense, with a 15.4 percent conversion rate. Through five games, opponents are only 10 for 65 on third down. Wisconsin's 4-for-15 performance on Saturday was actually the best of the season against Michigan after none of the first four opponents managed more than two third-down conversions.
• Michigan is sixth in the country in scoring defense at 12.4 points per game allowed, while Ohio State is first at 9.3. Last season, the Wolverines' second Big Ten game marked their third straight shutout. They haven't blanked an opponent yet this season but still have been stingy and held opponents to 14 points or fewer (Colorado having a defensive TD to reach 21) in every game.
• Michigan is tied for 12th in the nation in red-zone defense. The .667 scoring percentage by opponents reflects four scores in six trips. The Wolverines have not allowed a rushing touchdown on a red zone possession and the four scores are on three passing touchdowns and a field goal.
• Michigan is tied for 17th in the nation in interceptions with six. The Wolverines had two in the season-opening win over Hawaii as Delano Hill and Channing Stribling both returned their picks for touchdowns. Mike McCray had an interception against Penn State and the Wolverines added three more against Wisconsin – two by Stribling and Lewis' spectacular pick.
• Michigan is tied for fourth in the nation in sacks per game at 4.0. Of the 20 total, Chris Wormley leads the way with 4.0 while McCray and Jabrill Peppers are tied for second with 2.5. The Wolverines have 10 different players with at least one sack.
• Michigan is fifth in the country in tackles for loss per game at 9.4 while Miami is first at 12.0. Peppers leads the Wolverines with 9.5, Ben Gedeon is second with 6.0 and Wormley, McCray and Rashan Gary are tied for third with 4.5
• Michigan ranks 24th in country in rushing defense at 112.2 yards per game. Aside from Central Florida taking advantage of a few big plays to rack up 275 yards on the ground, the Wolverines have held every opponent under triple digits rushing with a season low of 64 allowed against Colorado.
