It all depends on the position. An elite QB masks a lot.
Lol, no. How good was Belichek with the Browns. Players are the important part.
I've answered this many times.
'94 Browns HC Belichick went 11-5 with two QB's, Testeverde (31) and Rypien (32) along with Nick Saban and they also beat the Patriots in their first match-up of the playoffs, but lost to the Steelers in the next round. The significance of the Steelers loss? It was the third time they had lost to Pittsburgh that season.
Steelers OC was the famed Ron Erhardt, who along with Ray Perkins, developed the Erhardt-Perkins (E&P) offense which is one of three offenses that essentially
all NFL offenses are based off of along with the WCO and Air Coryell. Steelers posed a threat offensively that year to all teams being that were balanced in their ability to run (#1) and throw especially from one back sets. Side note: the Steelers also had the #1 defense lead by DC Dom Capers, DAsst Bill Davis, LB coach Marvin Lewis, and DB coach **** LeBeau.
Pittsburgh would run 4 streaks along with 2 streaks & 2 outs to defeat Cleveland's Cover 3. Because you can't play the Cover 3 vs those routes, later the Browns switched it up to a Cover 1. The problem then lied with the Steeler's offensive talent that exceeded that of Cleveland's by their ability to beat them one-on-one. Also the Cover 1 is ineffective vs the run when you can't play 8 in the box b/c of a legitimate passing game and your defenders are spread out vs single back sets.
Solution, to somehow play a blend of Cover 3 and Cover 1. Now comes the melding of two incredibly intelligent minds in Belichick and Saban and with a collaboration between the two, and the concept of pattern-match defense was born. Although this concept was not installed in Cleveland, as Saban left for Michigan St. and Belichick would soon be fired the following year before being hired in NE, it thrives to this day among the brighter defensive minds in football and is the defense that both, Belichick and Saban, have used on their multiple championship teams.
This pattern-matching adjustment, better known as Rip/Liz in the mid-90's, brought together the zone and man-to-man defense into one concept. Pattern-matching has zone defenders play man-to-man
after receivers have shown their pass patterns, which the defenders typically pick up 5-7 yards downfield.
The reasoning behind this is that when offenses - like the '94 Steelers - want to attack a 3-deep zone they'll run TE's or slot WR's down the seams and to defeat Cover 1 they'll run picks and crossing routes. To defend this, the S's and LB's read the movements of of the Slot and the TE. When they run vertical, the .05 defenders and LB's run vertical with them, but if those receivers break outside then the defenders react with a zone and drop into coverage. In addition, the defense can add an extra defender in the box for the run or to spy the QB, which has also become a crucial factor in defending today's mobile QB's, spread offense, and the read option.
Also what must be taken into account are the circumstances ("The Move") that followed Bilichick's 11-5 1994 season in Cleveland. In 1995 Sports Illustrated predicted the Browns would represent the AFC in Super Bowl XXX and they started the season 3–1. Soon after Art Modell swindled the Browns from Cleveland and decided to move them mid-season. It was a decision that immediately crippled the the team, staff, their focus, their attitude, and they fell to 5-11.
