It's unfortunate for Obo that in the last round of negotiations that the NFL Players didn't get much larger rosters and a system that matches baseball and basketball for injury situations. I believe in the last round baseball was able to get a 5 day DL designation put in, and they can use it retroactively on a guy who happens to heal up quickly (which is especially good for a starting pitcher who is up in the rotation). I just think footballs rules on injuries have always been way too strict as far as the guy is out for the entire season, or he is cut. It's beneficial to the owners financially, but as far as team building goes, it would make more sense to be able to keep guys around for a bit and be able to use different designations. This really does screw Obo as far as playing this year goes (and thus his chances of making a living next season), but those are the rules. They don't have the option to put him on the 15 day DL, or to keep him on the roster because they have 60 roster spots and can just wait it out for him to get healthy.
Face it... it's an injury filled sport. Just turn the practice squad spots into normal roster spots and keep the gameday rosters at the same size. That way you can have 60+ guys on the roster. I'd say 63 is about right and makes sense. It will lead to less injuries if you increase gameday rosters by even a couple of players. Let's see the owners and commissioner walk the walk on that one. Would they be admitting that an 18 game schedule is stupid and that guys aren't suffering traumatic brain injuries if they let teams suit up way more players on Sunday for additional rotations and giving guys breathers? Too many times I've seen a guy have to play hurt because a team is OUT of players at a particular position on gameday. That doesn't happen in baseball because they have 25 guys on the roster (+ - depending on the time of year).
