10) Pat Shurmur: inherits a less talented team with no offseason to not only install a West Coast offense, but also a new defense. He then quickly has to coach up a second year quarterback(who is changing offenses) but then loses his best player to injury and apparent insanity. Despite this, he has a better record than Sparano...and has also beaten him in a head to head contest.
11) Marvin Lewis: refused to resign his contract unless Mike Brown gave into his "demands" for a practice facility and more scouts(ESPN has a larger scouting department). As is his way, Brown refused and Lewis eventually gave in...only to lose his franchise quarterback. At that point Lewis reshuffles his offensive coaching staff and hires Jay Gruden, a first time coordinator at any level. On top of all that he then is forced to start a rookie quarterback. Despite all this, his team is in the playoff hunt.
12) Jack Del Rio: his owner publically announced that he will be fired unless he makes the playoffs. On top of this, their is a major shake up in the front office as their GM refuses to sign a contract extension because the owner refuses to resign anyone who works under the GM. Despite all this, they do whats right for the teams future(though they probably wont be around to enjoy the payoff) and draft a quarterback. Del Rio has been told point blank he will be fired, and yet his team is still playing hard and has the same record as we do. With a rookie quarterback.
13) Hue Jackson: gets promoted to Head Coach after a single season as their coordinator, then loses his quarterback and his pro-bowl running back has missed time due to injury. Oh, and the guy who ran the team died in the middle of the season. Despite that adversity, Jackson rolled with the punches(something Sparano has never accomplished) secured another quarterback(again, never accomplished) and is now in position to win his division.
But hey! Our owner actually spoke to another coach! My god, do you have any idea what could have happened had he spoke to 2 coaches...the insanity! The mind breaking pressure of the situation! How could this all happen to one so young!?!?!?!
Edit: added in numbers for the running list. The Op asked for examples of other coaches succeeding where Sparano has failed, and each of those situations were more adverse than anything Sparano dealt with.
