You should try to make your points without distorting the facts.
San Diego drafted Sproles in 2005. Let's look at his seasons in San Diego:
- 2005: Sproles had 8 rushing attempts and 4 targets. Not surprising given the Chargers had Tomlinson, Turner, and Lorenzo Neal.
- 2006: Sproles missed the season due to injury. Just as well, since Tomlinson had the best season of his career.
- 2007: Sproles had 37 rushing attempts and 12 targets. The Chargers still had Tomlinson, Turner, and Neal. Tomlinson was still in his prime and had 60/475/3 on 86 targets in addition to 315/1474/15 rushing.
- 2008: Sproles had 61 rushing attempts and 34 targets. The Chargers still had Tomlinson, but Turner and Neal were gone, and they added Tolbert and Hester. Tomlinson had 52/426/1 on 77 targets in addition to 292/1110/11 rushing.
- 2009: Sproles had 93 rushing attempts and 57 targets, and he had 840 YFS and 7 TDs. Tomlinson fell off the cliff in this season, but still dominated RB opportunities with 223 rushing attempts and 30 targets. The Chargers still had Tolbert and Hester also.
- 2010: Sproles had 50 rushing attempts and 75 targets, and he had 787 YFS and 2 TDs. Tomlinson was gone, replaced by Mathews, and Tolbert
Norv was the Chargers HC for 4 years when Sproles was on the team, 2007-2010. When he got there, Sproles was coming off injury and had done nothing offensively in his first 2 seasons, plus he had Tomlinson in his prime as well as Turner and Neal. As Tomlinson declined from there, Norv upped his usage of Sproles on offense.
In 2009-2010 combined, with no dominant feature RB on the team, Sproles was #6 in RB targets (132), #4 in RB receptions (104), #2 in RB receiving yards (1017), and #1 in RB receiving TDs (6). This despite the fact that the Chargers were #17 in the NFL in pass attempts (1063).
He did have 96 punt returns and 195 kick returns, because he was good at those things. But your comment here was pretty much completely off base.
