From an Eagle fan, I would love for you to keep Tony Romo, sure he has had some great performances against us including the whoopin' from the beginning of the season last year, but the Romo experiment I think should be abandoned. I read some of your "post mortem" reports (excellent writing by the way) and there are some flaws with certain parts of your game including special teams and occasionally with your secondary, but I think that has more to do with injury over the course of the season then anything really endemic. Romo is the problem. He will always be the problem, and let me tell you breifly why that is.
WRs - It makes me want to vomit to admit it but you have one of the best receiving corps I have ever seen and the depth of it makes me queesy.
TE - Witten is really good. I hate you.
RB - MBIII has had a few issues (probably injury related) but is a solid power running back. Tashard Choice is a guy with a future and will be a winning component where ever he is on the field.
OLine - "Seems" to do a fine job providing time, and run blocking, but while it is big seems to have trouble defending DB blitzes and fast DE's coming off the edge.
Defense - has shown flashes of brilliance but the secondary needs to get buttoned up. D Ware. Nuff said.
So where do we lay blame on this team with exceptional potential. The blame lies at the QB position. The Sacks he takes and the fumbles are not indicative of a poor OLine but rather his inability to get the ball out on time and his "willy nilly" protection of the ball in mid-level passes. He sometimes puts the ball up where the receiver should be and not always where the receiver is. Bust on Mcnabb all you want about throwing bounce passes to receivers, but he rarely throws interceptions because of that propensity to try and protect the football...maybe not the receiver...but usually the football.
You need a young QB from the draft who you can turn into Franchise QB. Romo didn't get it done as a holder in '06, he didn't get it done against the Giants in '07, and you saw what happened last sunday.
Change should come from the top of the roster and you definitely need a guy with icewater in his veins who can protect the football and get it out in 3 or 5 steps. You need an answer and Romo ain't it.
