I haven't done a deep dig on more revealing stats, but this should give clues to how the game may play out on Saturday. I'm going to put some raw numbers from last year and this year from Rutgers and Michigan. You make your decision based on the info provided.
From the 2020 season defense:
Rutgers was 99th against the run, 81st against the pass, and 104th overall in total defense
Michigan 79th against the run, 96th against the pass, and 89th overall in total defense
From 2021 season defense (so far):
Rutgers 33rd against the run, 34th against the pass, and 17th overall defense
Michigan 30th against the run, 90 against the pass, and 62nd overall defense
Opponents offensive rankings:
Michigan has faced Northern Illinois (71st total offense), Western Michigan (84th), and Washington (112th)
Rutgers has faced Temple (92nd), Syracuse (110th), and Delaware (40th-FCS)
Neither team has faced great opponents, but Rutgers has played better defense. All 3 Michigan opponents have reached over 300 yards in total offense. Rutgers has held all three opponents to less than 260 yards. Just as people say you can run on Rutgers, you can pass at will against Michigan. UM had several 300-yard passing days against them last year and this year. Vedral threw for over 300 yards against Michigan last year. If Rutgers attacks Michigan the same way, I see why he can't have another 300-yard passing day. One thing I will say that's going to be a significant advantage for Rutgers is special teams. That advantage wasn't there last year. Also, the hostile environment would be huge, but Rutgers survived going against a long-time rival Syracuse without any problems.
I don't get why there is a 19 point spread other than one team being named Michigan. It is another close game if last year's score and this year's numbers are any indications. The deciding factor is who makes the least number of mistakes and executes when it counts.
When I have more time, I'll go more into the offense, personnel, and any other changes (Michigan's DC) that may impact the game.
