I am honestly not disappointed in this off-season so far. While the players aren't exactly all-stars, they are high potential signees, and the most important is that they are still relatively young. That's how you build a roster.
Also, I see a lot of flack towards Rhule but give the man a break and just let him do his thing. You seriously cannot expect Superbowl caliber results in just one season, especially with a rebuilding roster.
