I expect we're gonna lose game one because the offense won't have their starting tackles, which means Stafford will be unsettled, and I seriously doubt Reeder will do well vs Gibbs. So the storyline all over the media will be how the Rams fucked up by trading Jones. Electronic Ramsdom will be the same, people shitting on the trade and declaring how they were right that this was a poor decision.
But by the Shitter game they will have Speights in place (because Ratboy will fucking destroy Reeder) and while he'll have some rook moments I expect the defense will respond well to him. Because if you can play at ILB then you can play as a rook. As the season goes on people will realize he is excellent and fits what they want to do, and we'll find this defense is better than it was last season.
My biggest worry with Speights is can he hold up to the pounding. I think he is very instinctive. Not elite wheels but he moves well laterally and reads RBs nicely. So I expect he'll be about equal to Jones, where he is a bit less physical but gets out to the perimeter more. He won't be a sideline to sideline type but I think he is certainly fast enough to upgrade us over Jones in terms of mobility. And all this panic will be much to do about nothing.
