RBBC: Great for NFL teams, not so great for fantasy managers

What happend to the good ol' days of the NFL running back being the primary offensive weapon and focal point of the offense? Barry Sander, Emmitt Smith, Thurman Thomas to name a few Hall of Famers who carried the ball 300 plus times a year for their respective teams. The NFL has become a more physical sport with guys who are 300 plus pound being able to sprint the 40 yeard dash in sub 5 seconds, Shaun Rogers of the Cleveland Browns weighs in at 350 pounds, 6'4" and can dunk a basketball backwards, very impressive. With such physical specimens covering the football filed, our focal position in fantasy football(running backs) are physically deteriorating faster than ever.
The average span of a NFL players career is 3 1/2 years. Guys come out of college surrounded by hype and either do not produce as the NFL is the creme' de la creme' of the finest athletes around or they get hurt and fall of the face of the earth. Durability for the running backs in todays game is the biggest issue. Either 350 pounds guys will drop you at the line or safeties and linebackers get a full head of steam and take you head on. NFL teams flourish by having more than 1,2, or 3 serviceable running backs. The Dallas Cowboys have what I consider the best RBBC in the NFL. Marion "The Barbarian" Barber, Felix Jones, and Tashard Choice. Any one of these players could be starters for other NFL franchises. With Marion out on Monday 9/28/09 when the Cowboys hosted the Panthers, Felix Jones got the starting nod at tailback. Felix Jones started the game and showed why he can dominate a game with his cat like quickness and explosive break away speed. After Felix went down with an sprain to his knee, the Cowboys turned to their 3rd running back, Tashard Choice. Choice ran for 82 yards on 18 carries, 4.5YPC and scored a touchdown while also getting 4 receptions for 3 yards. The Cowboys were able to beat the lowly Panthers with help from their third string running back. Great for NFL teams as I mentioned earlier, you can never have too many good running backs on the same team. The Denver Broncos lost at least 5 running backs last year to the injured reserve.
My friend Ryan, who I've been playing fantasy football with in the same league for 3 years has all three of the Dallas Cowboys running backs on his roster. The question is who does he start if all of them are healthy, does he even keep all three when the starters get healthy and will receive the bulk of the carries. You as a team manager have 2 options, drop the third string running back and keep the starter and the primary backup or you can keep all three and play musical running backs. Team managers have played both running backs in a RBBC depending on the matchup, teams like the pace change a bruiser can bring compared to the speedy running back who does his damage in the open field. Lendale Fat tasted the end zone 15 times last year as he was the vulture and Chris "Every Coach's Dream" Johnson did most of the leg work using his lighting fast 4.24 40 yard dash speed. Deanglo Williams and Jonathan Swewart of the Carlina Panthers are very talented running backs and they are seeming to split carries more evenly this year than last, due to Stweart having some physical issues last year and Williams have a careere year. How do fantasy owners deal with such issues. Well the RBBC for the Tennessee Titans played itself out as Chris Johnson separated himself from Lendale by outperforming Lendale on the football field and making it a one horse race. (Even though Lendale lost 35 pounds in the offseason, White says its from not driking Patron on a very regular basis, Coach Jeff Fisher says its from not eating so much In N Out, I believe the coach.)
Fantasy owners have hated coachs such as Bill Bellichick and Mike Shannahan for years as they coached great running teams without a primary #1 rusher. Having your NFL team rush for over 2,000 yards is great, but if its 4 running backs each rushing for 500 yards a piece its not so great for fantasy managers.
The NFL is changing and we will see more specialty players enter the league as "gimic" formations such as the Wildcat become increasingly popular. So what can we do as fantasy owners, nothing really just go after the few running backs in the league who stay on the field for every down(Kevin Smith, MJD, S-Jax). This trend will not end any time soon and fantasy managers can expect more teams using this philosophy for years to come. So either deal with it by drafting accordingly(i.e. handcuffing) or wake up Sunday morning and flip a coin to see which RB in the committee your going to start.
