Do they run or pass primarily? I know nothing about their team
They have one good, not great, RB but he's versatile. Their OL looks again good, not great. They didn't appear to push MSU's DL around all that much but didn't seem to miss a lot of assignments either.
They have two good QB's. Both can throw it well. I watched their Mich St game last night. Unfortunately they do not have a lot of full game videos on youtube. Penix played that game and looked good. They threw an absolute TON of short passes and screens in that game. Very little downfield but Penix showed plenty of arm when they did. Together the two QB's totaled around 3,700 yards. UT's QB's totaled 2,640. However, they tend to wilt against good teams and D's. Against FBS teams with a winning record (they played only 3 believe it or not plus MSU at 6-6), IU had 2 TD's against 2 INT's. Overall they had 24 against 8. YPG went down by 30. Yds per attempt went down by about a yard to 7.6 ypa. UT was 8.1.
They have a pretty good receiver who runs well after the catch- Philyor. TE Hendershot looks like a real good player too. The others weren't too impressive to me vs MSU but they are big.
The stats tell a story with them when they play good teams. They throw more. They throw shorter.... and their run game largely goes to sleep. Against teams with a non-winning record which includes MSU they ran for 1275 and a respectable 4.21 ypc average. Against teams with a winning record they posted 230 yds with a 2.32 ypc average.
Both UT and IU got handled by the best teams on their schedule though IU gave PSU a good game and UT hung with Bama and UGA for a half. But down the schedule UT played better teams. The combined record of the teams they beat was 25-71. The teams UT beat were 41-44 with a UAB loss coming in their championship game. UT beat 4 teams with a bowl eligible record. IU beat no teams with a bowl eligible record. UT beat two teams ranked in the top 10 nationally in pass D.... by passing the ball. The highest ranked opponent in pass D that IU beat that I could find was Northwestern at 26.
UT currently ranks 16th in pass D which makes them the third highest ranked IU opponent in that category following tOSU and Michigan.
You can beat the stats and observations out a lot of different ways... I keep coming up with a UT win and a very favorable match up in both style and overall talent.
