Absolutely. Folks seem to forget that Jaleel Johnson wasn't a starter until he was a redshirt junior. It took him THAT LONG to get consistent enough to be a regular starter.
We have to remember that Lattimore is only a true Sophomore ... and we were forced to green-light his amount of playing time due to a lack of healthy, developed bodies at DT. Furthermore, we have a pretty active rotation at DT ... with reps mostly being split between Bazata, Lattimore, and M. Nelson. On third downs or obvious passing situations ... we've also been seeing Hesse and Reiff come in at DT too.
There are trade-offs with splitting reps. The positive is that guys tend to be a bit fresher. However, the negative is that a D-linemen doesn't see as many reps to get a "feel" for how the O-lineman is playing him. That can make it harder for the D-lineman to make in-game adjustments to be successful. Furthermore, the fewer reps you see ... the fewer reps you have to improve from.
At this point, I would surmise that the biggest factor impacting the DT play simply has to deal with inexperience at the position ... given that 2 of the 3 top DTs are "newer."
Lastly, if you look to the future ... we get Nixon on campus this spring if everything goes according to plan AND we'll be getting Linderbaum and Shannon next summer/fall. Those are some fine additions to the DT group!
