Amendola’s plight is not that much different from the plight of Wes Welker coming out of college. Here is Wikipedia’s account of Welker’s start:
After his senior season at Texas Tech, Welker went undrafted in the 2004 NFL Draft but ended up signing as a free agent with the San Diego Chargers.[8]
[edit] Professional career
[edit] 2004
Despite making the Chargers' roster out of training camp, Welker was cut after the first week of the 2004 season and signed with the Miami Dolphins, where he was mostly used on special teams. Playing against the Patriots on October 10, 2004, Welker became the second player in NFL history to return a kickoff and a punt, kick an extra point and a field goal, and make a tackle in a single game.
[edit] 2005
During training camp at the beginning of the 2005 season, Welker was promoted to the third wide receiver spot after Chris Chambers and Marty Booker. He finished the season with 29 receptions for 434 yards and no touchdowns. He also had 43 punt returns for 390 yards, a 9.1 average, and 61 kickoff returns for 1,379 yards, a 22.6 average. These ranked 11th and 20th in the NFL, respectively.
[edit] 2006
After rumors that he would be cut during the preseason, Welker started off being the lone bright-spot of the struggling Miami Dolphins offense. Through five games, he netted a team-high 29 catches and team-high 299 yards. During Week five, he was a huge target for back-up quarterback Joey Harrington, recording a then-career high nine catches for 77 yards in the 20-10 loss to the New England Patriots. On the season, Welker had a team-best 67 receptions for 687 yards and one score. He returned 48 kickoffs for 1,048 yards (22.2 average) and 41 punts for 378 yards (9.2 average).
[edit] 2007
On March 1, 2007, the Dolphins offered Welker, a restricted free agent, a second-round tender (the second-lowest tender) of $1.35 million for a one-year contract. The Patriots, who were interested in Welker, had originally considered signing Welker, a restricted free agent, to an offer sheet which Miami would have had seven days to match; according to The Boston Globe, that sheet would have contained a poison pill provision which would have made the offer difficult for the Dolphins to match.[9] Ultimately, however, the Patriots decided not to use such an offer, and traded the Dolphins their 2007 second- and seventh-round draft picks for Welker.
