Did you even read the thread? Based on this post, I have to assume you didn't.
There is risk. The risk is that they will not address the position further. The risk is that come week 8, we could be looking at the team signing guys off the street because both Gregory or Smith are on the shelf. It's not as if the team hasn't done this in the past.
As far as not understanding how this effects the Offense, well, it's another wasted season and the excuse will be "Hey, we tried to address the problem." Same old story. In truth, I don't understand why this has to be explained but fine, it's explained now. The window with this team is probably two to three years now, IMO. After that, we will likely be replacing parts and we really can't afford to just throw away seasons because we don't address important weaknesses, if we want to have a chance to win.
