re: How long until our D-line is dominant again?

It was fairly strong this year and will likely be dominant next year, although we might be playing 210lb linebackers behind them.

The trouble comes the year after next. All of the DTs on that team, which takes the field in 21 months, are in high school right now.

We won't be competetive in the SEC with second year DTs, not unless we get extremely lucky.
