I too only watched a couple LT games, but did follow them in the box scores weekly.
The biggest liability in the game is going to be the SMU D. I don't think the coaching situations is as big of a deal compared to their issues on D. We know that SMU D isn't good, teams have their way with them by ground or air...although some of the Os SMU has played against are pretty good.
Some of the LT games have been close losses, but they also had misleading win vs Rice (won by 14 yet were outgained by Owls - tied 28-28 late LT took 7 pt lead with 1m left then got a pick-six to end game). Rice had their 3rd highest CUSA yardage output vs LT. They lost in OT to SM yet were outgained by 140y. SMiss had their 3rd highest yardage against LT. They lost by 1 to North Texas but were outgained by 100y. UTEP's inept offense drove to the LT 27, 20 and 15 on three of their first 4 drives of the game but came away with zero pts because they are ofcourse UTEP. Still UTEP's 410 yards were nearly double what the Miners had averaged in their other 11 games.
I just haven't seen much to like about LaTech this year. They have a good running game. Think their D isn't as good as it might appear at first glance. Their D looked great vs UTSA, but UTSA has no O (held to single digits in 3 of their final 4 games). I recall LT not being shy about going for it on 4th down often, so that is something. They also seem to have some FG kicking issues in pressure moments.
