Indeed, the most impressive stat from Arthur Smith’s tenure might be his red zone efficiency in both 2019 and 2020. In 2019, the Titans led the league with an incredible 75.6% RZ efficiency. Most assumed that was an aberration and would be nearly impossible to replicate, but they did: Tennessee finished with a nearly-identical 75.0% RZ efficiency in 2020 (2nd in the NFL).
The Titans could bring Clowney back at a reduced price.
The Falcons pulled in a big name at defensive coordinator. And they did not just pull him out of the names of hot coaches. They pulled him out of retirement.
