WB's new qb, Harrell, kept them in that game & WB's Wing T, really can make at team's defense look pretty bad. The last couple of years, they definitely had a near miss against Smith.
As for LT compared to other 4A teams, I don't get to see those teams outside the 757 but you can bet LT will be like a lot of teams and make big improvements after their 1st game.
As for 757 being down, I think some of the 5A & 6A are as you state but I think the story for this area will be Deep Creek & Kings Fork. Deep Creek nearly beat LT last year in the playoffs, their JV only lost to Smith in OT. And there are Sports writers in our area that believe Kings Fork may have the most talent in the Southeastern District!
