Tuck's takes: Ravens rookie safety needs help in coverage and more

With no football to play for the first time in 18 years, former pro Ross Tucker is passing the time reading about his favorite sport. What follows are a few links to NFL -related articles he found and his take on them.

It is never a good sign when an NFL coach calls you stiff. Ravens defensive coordinator Rex Ryan recently used that word in reference to rookie safety Tom Zbikowski , the former Notre Dame star. Though it is not necessarily the kiss of death, it is definitely NFL-speak for lacking in athletic ability.

I should know. I was called stiff on more than one occasion during my career. And you know what, they were right -- I was pretty stiff. That doesn't mean I couldn't get the job done; it just meant I wasn't as fluid and didn't move as well laterally or in space as the coaches would have liked.

Agility in the open field is much more important for a safety and special teamer like Zbikowski than it is for an interior lineman like I was. Ryan 's contention that he would like to see Zbikowski "change direction a little bit more" can only be seen as a sign that Zbikowski has not made a good impression in coverage thus far for the Ravens . Though losing some weight, like Ryan suggests, could help Zbikowski a little, my experience tells me it is unlikely to make a dramatic difference in his fluidity.

All but seven NFL teams voted in favor of the new rule that allows one defensive player to have a radio in his helmet on every play, mimicking the current way in which the offensive plays are currently relayed to the quarterbacks. There are a number of potential problems with this rule, and I am surprised more people haven't brought them up.

One of the major problems is that unlike on offense, where the QB is always in the ball game, defensive substitutions are much more frequent in a league where defensive coordinators strive to match personnel with the opposition. Clearly every team, like the Packers with Nick Barnett and Nick Collins, has certain players that are typically on the field for every defensive snap. That is not the problem. The problem becomes if and when that player gets injured. Just because Barnett and Collins are three-down players doesn't mean their backups would be as well. Teams will still have to have all of the hand signals in place as a contingency plan for all the different situations that could take place.

It also will be very interesting to see how well these in-helmet radios are really made and how well they will hold up at a head-rattling position like linebacker. Unlike quarterbacks, who rarely get hit head to head because of the penalty involved and the potential fines, defensive players in the front seven make helmet-to-helmet contact on almost every play. Those things better be built to last.

The fact that no players can wear a helmet with a radio in it on special teams' plays becomes a logistical nightmare for the defensive player who wears the helmet. Some starting defensive players stay in for special teams plays like punts, field goals and extra points. If the coaches want to keep a player like Barnett in for that play, which is certainly their prerogative, he will have to switch to a non-radio helmet before the snap. That seems pretty ridiculous, doesn't it?

Anyone into the business side of the NFL has to respect the way the Titans are handling their negotiations with stud defensive tackle Albert Haynesworth . They gave him the franchise tag earlier in the offseason and have not been able to reach a long-term contract agreement. His agent says Haynesworth will sign the tender if the Titans agree not to place the franchise tag on him again in 2009.

There is no denying Haynesworth is a dominant football player and quite possibly the Titans best player. That being said, the Titans are smart to be hesitant to give a huge contract to a player who has proven to have both anger-management and effort issues throughout his career. They could write some language into the contract to protect themselves should Haynesworth decide to go on another face-stomping rampage like he did with Andre Gurode .
