Last season's biggest disappointments came in the form of San Diego's top free agent receivers Eddie Royal and Robert Meachem.
Royal concluded his 2012 campaign with 23 receptions for 234 yards and a touchdown while Meachem finished with just 14 receptions for 207 yards and two touchdowns. Both proved to be bust signings and face an uphill battle in redeeming themselves.
This season, however, the three players destined to disappoint include OT Max Starks, SS Brandon Taylor and OLB Larry English.
Starks, formerly of the Pittsburgh Steelers, was signed as a free agent in May to help solidify the left tackle spot of the Chargers' offensive line, but judging from how much more playing time King Dunlap has been getting in training camp and in the preseason, it's looking more and more like Dunlap will be the starter come Week 1.
Unless Dunlap performs horribly and forces Mike McCoy to make a change, Starks can already be viewed as a wasted signing merely brought in for veteran depth.
Taylor finds himself in a similar situation at strong safety. The third-round pick from a year ago suffered a torn ACL last season that forced his recovery process to continue into the start of camp and the time off has caused him to lose ground in the competition for a starting job next season.
Taylor was drafted particularly high by A.J. Smith in 2012 for the sole purpose of one day becoming the starting strong safety for San Diego, but now that the team appears to be moving forward with Marcus Gilchrist, it doesn't seem likely that Taylor will see much of the field anytime soon.
In English's case, it's like listening to a broken record when speaking of the 16th player taken overall in the 2009 draft. Since his rookie season, English has failed to live up to expectations as a first-round pick and 2013 will be no different.
Even with the injury to Melvin Ingram, English will be a nonfactor despite initial talk that he'd be looked to for help in the pass rush in Ingram's absence. For that reason, English will be the biggest disappointment of 2013.
Winner: Larry English
