With the first practice of spring set for Monday, new Bengals head coach Zac Taylor's installation on both sides of the ball has been on fast forward. Offensive coordinator Brian Callahan figures 85 percent of his scheme has been installed while seven-year safety Shawn Williams, the Generalissimo of the secondary now that George "General," Iloka is gone, puts defensive coordinator Lou Anarumo's playbook at 90 percent complete.

But don't go nuts if you see anything radically different on the offensive line in Monday's drills, the first session of what is otherwise known as "Organized Team Activities," (OTAs). Callahan warns what you see then doesn't mean it is what you'll see Opening Day in Seattle. All eyes are on first-round pick Jonah Williams and if he'll play left tackle, left guard or elsewhere and if that would mean moving a guy like incumbent left tackle Cordy Glenn inside. Who knows? We won't know Monday.

"We'll play with a bunch of different lineups," Callahan said Tuesday. "Anytime you're talking about offensive linemen, they all have to swing inside and outside. Guards have to play center and centers have to play guard.

"We have the flexibility to give us the five best players where ever they fit. It's going to be really hard to know that until we put pads on. The pads are always the great equalizer," Callahan said of a day that won't come until nearly August. "Monday is not a foreshadowing of week one in September. We're going to mess with a bunch of different combinations. Where we start on Monday could very well be where we start come September. It could very well not. A lot of football between now and then."

During the OTAs, team and special teams drills are allowed as long as there is no live contact. Helmets can be worn, but no other pads.
