I was doing a little thinking about SMU and their 4-2-5 base. I think their defense is giving up 3.3 or 3.4 yards a rush which is outstanding. However, if you think about the 4-2-5, schematically, it should be vulnerable against the run. So I did a little digging and it turns out that their leading tacklers are a bit skewed in two positions.
Leading tacklers (solo) for SMU: Name-total-position
1.) Onu, Mikial -29-DB
3.) Clemons, Rodney-24-DB
4.) Wyatt, Jordan-17-DB
5.) Lawler, Justin-16-DL
9.) Dimarya, Mixon-9-DL
I'm going to go back and watch some of their previous games to get a better idea, but I have a hunch that we're going to find success against their defense. If their top 10 tacklers are dominated by linebackers and DBs, that means teams are getting to the second level with their Oline and able to get hands on the DBs and Backers. It also could mean that WRs are running free in the secondary. Again, I'm not sure, but this could quite possibly be the case. I will say this about their run defense averages. They might be a tad bit inflated due to varying competition level.
SFA avg. 2.1 against SMU
UNT avg. 2.6 against SMU
TCU avg. 5.6 against SMU
Arkansas State avg. 4.9 against SMU
Uconn avg. -0.2 against SMU
Now that it can be concluded that better competition equals more success against their run defense, let's avg. the weaker teams' rushing and better teams' rushing yards.
SFA+UNT+UConn= 4.5/3 =1.5 yards allowed per rush
Arkansas State+TCU=10.5/2= 5.25
What we have here folks is a run defense stat-line that's inflated due to easier competition (I hope). If you're truly giving up 5.25 yards a carry, DBs and LBs will be your leading tacklers on the team. That's not stopping the run, that's allowing teams to get to the second level consistently. I'm feeling more and more confident about running the ball against SMU.
