On paper, it sure looks to be the best. But, they have to prove it on the field. They've been very prone to penalties for as long as anyone can remember. There's plenty that can go wrong, especially with so many new players, and the potential for some to be unhappy with the role they end up with. And, there is still some question as to whether Castle will really go through the entire season airing the ball out 20+ times a game. In 2017, Lakeland aired the ball out pretty well against eventual state champion Venice in the spring game, too. People thought Kevarris Thomas was going to be a legend. But, eventually, the offense went conservative, reverted back to a one-read passing game, and dried up the last few games of the season. If that happens again, and they revert to running the same offense they've had for years, I don't think the OL and backs are good enough to overcome the holding penalties and lack of a running threat at QB to score with ease.
But that's the totally cynical view. The smart money is on this being the best team they've ever had, by far.
