I remember that Comcast commercial during the beginning of the season that had all key players. Each plaery had a key to winning for the season (believe Davis said "its the TDs" and Fletcher said something like "its the hits"). At the end of the commercial RG3 states "Its the Team". Well how good is the team and who is at fault?
Their very little reason (if any) to retain this coach (staff). Shanny has a record comparable to Danny and Vinny during the same time period (might be worse). The reasons for his record are filled with lame excuses; salary cap, RGs knee; Danny's fault etc. Great, even good coaches, can overcome these obstacles thus I'm not going through all the coaches that have created solid (even .500) teams with these issues previously mentioned.
Could you be a failure at your job for 3 out of 4 years and get an extension? An please note Shanny's only successful year was due to an rookie QB (you can argue) who had one of the greatest Rookie seasons in NFL HISTORY! I always tell people no QB should or will continue to rush for 800+ yards w/ 8 TDs. Thus as an coach your duty is to create a team around this great QB.
Now the defense is worse, special teams worse, and offense of course not like last year (mainly due to the absent QB rushing yards).
Take Chip Kelly for example (Innovative College Head Coach). I would argue the two teams have about the same talent but Chip's offensive plays with an offensive desperation and due to the fact his defense is bad (worse then the Redskins), not only is this smart coaching, it works (see Shanny's year 1 record then Chips). Now Chip Kelly has out coached Shanny twice, in one year, with no excuses.
Rekskin fans are too smart to take the bull$*** excuses, meanwhile other coaches are WINNING in year one...Fire this LOSER COACH and GET INNOVATIVE.
