I'd have to give it to Mark.
Richard Todd had an amazing supporting cast. As someone eluded to earlier, the guy did in fact under perform. Give Mark a supporting cast as he did in '09 and '10-he has the ability to do something special. {Playoff games and many come back wins in '10}.
They both had very good defenses but of course huge edge to Todd with the Sack Exchange bunch.
Sanchez is still my guy on this debate on everything he's enduring. IMHO, i feel this guy with Mourningwig as OC, will be in the Alex Smith category when it's all said and done.
Mark as did Alex has been stripped of any sort of confidence. The team-The fan base-The organization have no faith but are tied to him. MM has a huge and difficult task ahead of him as did Jim Harbaugh and Greg Roman rebuilding A.Smith.
As to the Nagle>Sanchez

Look at the stats and that supporting cast he had in '92. That was coming off a playoff appearance in '91 with Kenny O. I wish Sanchez had that talent on that side of the ball this past season.
Freeman McNeil-RB
Rob Moore-Wr
Al Toon-WR
Chris Burkett-WR
Terrance Mthis-WR
Johnnie Mitchel @ T.E
Stout O-Line
and a very under rated Defense.
Browning Nagle was the all time biggest NYJETS bust of all time-bar none.
