Obviously, he is an all time great and deserving 1st ballot HOFer. However, I think some people are overrating him in this thread and, inevitably, in the media due to the recency effect.IMO it is not debatable that Jim Brown, Walter Payton, and Barry Sanders were better and are the top 3 RBs of all time. I think there are strong arguments to be made that Emmitt Smith, Eric Dickerson, and Marshall Faulk were better. And, while it is impossible to compare across such divergent eras, I'd rank Gale Sayers higher also. I'd probably rank Tomlinson #8 on my all time RB list.
I think Walter Payton and LaDainian Tomlinson were extremely similar in an awful lot of ways. They were both tremendously versatile (as runners, receivers, blockers, and even passers). They both were good soldiers on perennial losing teams early in their careers, and stuck with their teams until they turned things around and enjoyed success. They both played with tremendous heart, and were well respected, high-character guys off the field. They even both had that same little stutter step in the open field — probably because Tomlinson copied it from Payton.Rather than being "not debatable" as to which was better, I think they're pretty even.
I agree Tomlinson, like Payton, was very versatile and well rounded, and I already agreed he is a top 10 RB. However, I think Payton was better in every phase of the game: running, receiving, blocking, passing, returning, and kicking, as well as intangibles like leadership.Tomlinson was better passing in a smaller sample size, but Payton threw nearly 3 times as many passes and was actually the Bears' emergency QB; I believe he had more ability as a passer.Payton was an excellent kickoff returner in a small sample size and punted once for 39 yards. Tomlinson didn't do those things, so it seems safe to assume Payton was better at them.But, while those skills (passing, punting, returning) are part of being well rounded, they really shouldn't factor much into a comparison of RBs. The most important RB skills are running, receiving, and blocking.Unfortunately, there are no numbers to measure blocking, so there is no way I know of to prove which guy was better. My own impression from watching them play is that Payton was better, and I believe that is supported by reputation. But I think we have to set this aside, given there is no way I know of to quantify blocking effectiveness.So it essentially comes down to running and receiving. Payton ran the ball a lot more times (3838-3174) for a lot more yards (16726-13684) with a higher average per carry. And consider how each of them performed compared to other RBs on their teams

ayton averaged 4.36 ypc over his 13 year career. During that 13 year span, all other Bears RBs combined to run for 3.91 ypc.During his 9 seasons with the Chargers, Tomlinson averaged 4.34 ypc, while other Chargers RBs combined to run for 4.61 ypc. During his 2 seasons with the Jets, Tomlinson averaged 4.06 ypc, while other Jets RBs averaged 4.05 ypc.I don't see how anyone can argue that Payton wasn't a better runner than Tomlinson.Payton had a huge edge in yards per reception. Tomlinson caught a lot more passes and had narrow edges in receiving yards and receiving TDs, but the raw numbers reflect differences in era and, to a lesser degree, team philosophy. Payton led the Bears in receptions 6 times and was second on the team 5 other times. IMO he was clearly a better receiver.And Payton was better despite playing with a poorer supporting cast on offense. Bears QBs only made the Pro Bowl one time during Payton's career. Meanwhile, Tomlinson played most of his career with Brees and Rivers... heck, even Sanchez was better than the QBs Payton played with. Payton never played with even an 800 yard receiver; no Bears WR or TE made the Pro Bowl during his career. Tomlinson played alongside Gates and Vincent Jackson. Both Tomlinson and Payton generally played with poor OLs, but Payton's OL made 5 Pro Bowls in 13 seasons, compared to 10 Pro Bowls in 11 seasons for Tomlinson's OL. Plus, Tomlinson got the benefit in his prime of having Lorenzo Neal as his FB.Payton was also more durable, missing only 4 games in 13 seasons and starting 178 straight games, the NFL record for RBs. This despite the fact that Payton was known to dish out a lot of punishment on his runs.Like I said, I don't think it's debatable.
And as much as I loves me some Gale Sayers highlights, I don't think he's in the same tier as all the other guys you mentioned.
Sayers only played 2 games in each of his 6th and 7th seasons due to injury and retired. But he was 1st team All Pro in each of his first 5 seasons. In those 5 seasons:1. He was in the top 5 in rushing yards in each of those 5 seasons and led the league 2 times.2. He was in the top 3 in rushing yards per game in each of those 5 seasons and led the league 3 times.3. He was in the top 4 in rushing TDs in 4 of those 5 seasons.4. He was in the top 4 in yards from scrimmage in 3 of those 5 seasons and led the league 1 time.5. He was in the top 5 in all purpose yards in each of those 5 seasons and led the league 3 times.His production per touch was amazing:5.0 yards per carry11.7 yards per reception14.5 yards per punt return30.6 yards per kickoff returnIn addition to excelling as a RB, he is the best kick returner of all time, despite what a lot of people say about Devin Hester nowadays.Aside from all that, consider the recognition Sayers has received for how he ranks in various all-time lists:1. He was named the all-time NFL halfback in 1969 (NFL's 50th anniversary).2. He was one of 7 RBs named to the 75th Anniversary Team in 1994.3. I have seen references saying he was named to the All-time NFL Team in 2000, but I can't find that team online, so I don't know much about it.4. He was #22 on the NFL Top 100 Greatest Players list released in 2010, behind only 4 RBs: Brown, Payton, Sanders, and Nagurski.As far as I can tell, he has been chosen as being among the very best RBs of all time for every official all-time team selected since the middle of his career more than 40 years ago. I'm surprised you would say he doesn't belong in the same tier as any of the RBs I named.
