It's good to have the CB depth. We still need to see it from Long. If one of the 4 CBs gets dinged they will need another. I don't think you want to go into a game with 3 CBs even with versatile safetys.
It was good to hear Talib say he always thought Dont'e Deayon had sticky coverage. It's Hall's second year with Morris. I would expect that brings familiarity with the system and an easier transition to playing. That and 4.3 speed might come in handy in a passing league with a 20 game season. Anticipate attrition.
Koski makes me think of Amendola.
The LB depth with Kiser and Lawler is good to have.
Maybe Trishton Jackson is in talks with other teams, Bengals? Lions? Packers?
