Agreed - all around improvement has allowed some of the young talent to emerge. I suppose people will still knock the team’s scouting and often rightfully so, but they certainly find some good DBs.
I would say better play from the secondary has allowed the blitzes to be more effective. Two guys in particular have got their A game back: Loffler is looking more like he did two years ago, and Randall is back to being a shut down corner. Then you add a monster named Bighill and you get what we saw yesterday.
I just remember watching a game at Sky Dome where he was very effective - particularly at running short slants and picking up good yardage every time. Harris has so many roles - it would be nice to spread it out a little more.
