If you want to put a frown on Mike Zimmer's face, mention the NFL rule against teams practicing press-coverage techniques during organized team activities, minicamp and the first two days of training camp.
The Vikings coach and noted defensive backs sage has called the rule — which was part of the crackdown on offseason contact to promote player safety — "ridiculous" and harmful to the careers of young cornerbacks who need the practice.
However, if you want to turn Zimmer's frown upside down, remind him how Xavier Rhodes has looked in his off-coverage techniques, especially on one particular play during Day 2 of the Vikings' three-day minicamp on Wednesday.
Playing his customary right corner spot, the 6-1, 218-pound Rhodes lined up off the line of scrimmage, per NFL rules. Receiver Charles Johnson, who isn't small at 6-2, 217 pounds, got a free release and was racing toward Rhodes as quarterback Teddy Bridgewater dropped back to pass.
"I'm looking at [Johnson's] hips," Rhodes said when asked what he's reading at that point. "I'm looking to see if he's going to turn his hips or is he going to keep them straight and do a double move and keep going up the field."
Johnson turned his hips inside at approximately 10 yards.
"When he turned his hips, that means I go," Rhodes said. "So I went."
Rhodes closed on Johnson with confidence, fluid fundamentals and enough arm length to please a defensive end.
