So... Is Bill O'Brien as good a teacher as Charlie Weis?
Remember when Todd Haley was the HC of the 2010 Kansas City Chiefs? They went from 4-12 in 2009, to 10-6 AFC West champs in 2010. He had Charlie Weis as his OC & Romeo Crennel as his DC.
Weis was named offensive coordinator of the Kansas City Chiefs for 2010. In Weis's first year, the Chiefs improved from a record of 4–12 to 10–6 and returned to the playoffs after winning the AFC Western Division. With Weis as offensive coordinator, the Chiefs had the NFL's best rushing attack, averaging an impressive 165 yards per game on the ground. Offensively the Chiefs ranked 9th in total offense, 11th in points per game, 1st in rushing, and 28th in passing. The Chiefs also sent four players on offense (WR Dwayne Bowe, RB Jamaal Charles, QB Matt Cassel and OG Brian Waters) to the Pro Bowl. Bowe and Charles made their first ever trip to the Pro Bowl. Weis has also been credited with the improvement of QB Matt Cassel who had a career year throwing for 27 touchdowns and only 5 interceptions in 14 games.
Crennel on the other hand didn't do to well as the Chiefs were avg on defense. 14th in total defense. 11th in points allowed. 17th in passing yards per game. 14th in rushing ypg...
