LONDON — When Raheem Morris speaks, the words tumble out, as though he’s been given a time limit on how long he can talk and he’s trying to fit in as many words as possible in the allotted moments.

When Josh McDaniels speaks, it is with a guarded, careful cadence, a familiar one to fans of a certain New England-based team that makes it clear he is measuring every syllable, wanting to get out just the right message.

The two men were born just over four months apart, and are the youngest head coaches in the National Football League, both rookies in their jobs.

And their results thus far, like their backgrounds and the men themselves, could not be more different.

McDaniels’ Denver Broncos are 6-0, arguably the most surprising team in the NFL to this point. Morris’ Tampa Bay Buccaneers are 0-6 and seemingly fading from the collective football consciousness.

Two weeks ago, McDaniels trumped longtime mentor Bill Belichick when Denver beat the Patriots in overtime.

On Sunday, Morris will be looking for his first win, one that would be a significant feather in his cap, against the same New England team.

They are only 33, an age which was once considered far too young to be an NFL coach, and each has endured his share of problems early on in their tenures.

Morris is from Irvington, N.J., a hardscrabble town with a high crime rate. Football was his love, and when his parents took it away from him his sophomore year of high school because of poor grades — he brought home a C average, enough to keep him eligible by school standards, but not his family’s — it made him focus on the game and his studies.

He was good enough to play safety and cornerback at I-AA Hofstra, and some feel, good enough to play professionally. But Morris had discovered his interest in coaching years earlier, and stayed at Hofstra as a graduate assistant, getting his start in his career.

McDaniels was raised in Canton, Ohio, a middle-class city that is the home of the Pro Football Hall of Fame. His father Thom is a high school coaching legend in the state, and McDaniels began accompanying him to the field when he was in preschool.

He played the game at Division III John Carroll, which is known more for cranking out coaches (Don Shula is an alumnus) than players, and used his father’s connections to get a graduate assistant position at Michigan State, then coached by Nick Saban.

When McDaniels could no longer serve as a grad assistant, Saban recommended him to his friend, Bill Belichick. McDaniels spent eight years learning from the man considered the best football coach of this generation.

In comparison, Morris moved around a bit. After Hofstra, he spent two years at Cornell, then returned to his alma mater as defensive backs coach. One season later, he was with the Buccaneers, working as a defensive assistant and assistant defensive backs coach.

By 2006, he was on the move again, back to the college game, as Kansas State’s defensive coordinator.

He was there for a year before he returned to Tampa Bay as defensive backs coach.

When Morris was named as Tampa Bay’s head coach a day after the stunning firing of longtime coach Jon Gruden, he was the Bucs’ defensive coordinator — a job he had held for all of a month, elevated by Gruden after longtime coordinator Monte Kiffin went to Tennessee to coach with son Lane — it was as though he came out of nowhere.

Just a few days earlier, Morris had interviewed with the Broncos, and was reportedly one of five finalists for the job McDaniels got.

It is clear that while McDaniels was clearly ready for everything that would be thrown at him as a head coach, Morris may have been rushed into his gig by a Tampa Bay organization bent on not letting another great young coach get away.

(The Buccaneers had current Steelers head coach Mike Tomlin on staff for five years before he left to become the Vikings’ defensive coordinator and then went to Pittsburgh a year later. About a week after promoting Morris, Tomlin won the Super Bowl.)

Morris, bent on making his team younger, released mainstays like Derrick Brooks, Kevin Carter and Warrick Dunn, all players older than him. Morris maintained on Saturday that he wants the young players to guide this team going forward, but young players make more than their share of mistakes.

Things in the NFL change rapidly. Super Bowl winners one season miss the postseason the next, Pro Bowlers see their star fall like a comet, this year’s hot coaching prospect becomes yesterday’s news.

Five years from now, things may be different, and Morris may prove to be a tremendous find. But right now, the young coach and his equally young roster are enduring their growing pains together, while his contemporary, McDaniels, is taking the NFL by storm.

No matter how fast the words come out when he talks about his team, there is one thing Morris can’t avoid: His team is 0-6 and needs something — anything — to get things turned around.
