With Dontae Johnson now questionable or worse with a hip injury, it looks very possible that the Seahawks will end up starting two rookies in Denver — Tre Flowers joining Shaquem Griffin.
Flowers, a 6-3, fifth-round pick who converted from safety to corner for Seattle, played a ton in the preseason as he learned Pete Carroll’s very specific technique (kick-step, etc.). And he got a lot of up-close tutoring from the coach himself.
