This is one of the better posts in this thread (thank you for taking the time to explain your rationale)... but you still couldnt avoid an attempt at humor (this is beside the point).
This STL team with Bulger at the helm has been ridiculed to death. I think it is fair to say that they couldnt possibly do any worse (since this is all due to the o-line problems). You just cant go out and pick up a good offensive line... that is shot for the rest of the season imo. The mere fact that they are giving Green a shot shows that they recognize that they cannot when with the current plan of attack. A potential positive is that Green might provide something that Bulger cannot. It was mentioned (surprisingly by only one person and then completely ignored... everyone too busy trying to one-up the latest quip) early that Green is familiar with the Saunders offense having run it in KC. There is a small possibility that Green might fit Saunders scheme a little better, given his experience, and possibly give them an opportunity to compete.
Change, whether is works or not, is a positive (better to the alternative of sticking to what they know doesnt work... whether its a desperate move by the coach or not... Bulger wasnt winning games). Regardless of Greens health concerns he has been cleared to play. Green may not turn around the Rams season (will certainly not argue that he will) but from a fantasy standpoint (this is the only interest I have with the Rams) there is the potential for a player or two to benefit. Randy McMichael could be that player. Here is Greens only significant preseason action... (granted it was a 2-minute drill)

Does this mean anything? Who knows but you cant deny that there is the potential for someone to benefit fantasy wise from this move and I think it is shortsighted to ignore the possibility because Green is suffering from dementia and sucking food out of a straw...
Instead of 100 replies to compete for the best joke... is it too much to ask for a "lemons into lemonade" type discussion. I just dont see the point of repeating the same joke over and over again with a little different spin.
