Andy Reid had his share of busts in free-agency signings, including paying $60 million to Nnamdi Asomugha. (US Presswire)

This is a series that looks back on Andy Reid’s career as coach of the Eagles and the best and the worst of his 14 years in Philadelphia.

Andy Reid’s five worst free-agent signings in descending order:

5. QB Mike McMahon, 2006: For some reason, Reid thought McMahon would be a solid backup for Donovan McNabb the year after the Eagles went to the Super Bowl. McMahon had started some games for Detroit and he was a veteran who had played in a similar offense, so … Well, the move blew up in Reid’s face. McNabb got hurt, and the Eagles went 1-5 in the games McMahon started. Just one season removed from the Super Bowl they didn’t even make the playoffs.

4. QB Vince Young, 2011: What was Andy Reid thinking?

3. OT Demetress Bell, 2012: The Eagles needed to replace Jason Peters, the best left tackle in football, and they ended up signing a guy who couldn’t beat out King Dunlap. Bell was handed a starting job in training camp this season, but he quickly lost it. Then, when he had to play during the season because Dunlap got hurt, he almost got Mike Vick killed. It’s uncertain whether Bell just didn’t pick up the system or just wasn’t very good, but his utter failure to fill Peters’ shoes was something the Eagles couldn’t overcome.

2. CB Nnamdi Asomugha, 2011: Asomugha was given a mulligan for his first season with the Eagles, when he was late in joining a defense going through a major transition. But there was no excuse for his terrible play this season, when he was used and abused by almost every NFL receiver he was matched up against. Asomugha came to the Eagles with the reputation as being one of the top two or three CBs in the league, but he was so bad he ended up getting benched in the season finale vs. the Giants. If Asomugha is going to be with the Eagles next season, he’s going to have to take a big pay cut and restructure his five-year, $60 million contract.

1. S Blaine Bishop, 2002: This former Houston Oilers Pro Bowl safety signed a three-year deal with the Eagles and was supposed to team with Brian Dawkins and give them a dynamic one-two punch at safety. Unfortunately for the Eagles, Blaine Bishop played more like Joey Bishop (google “Rat Pack’’ if you don’t know who he is) and he was gone after just one year. Probably the most lasting memory of Bishop came in the NFC Championship game defeat to Tampa Bay, with his woeful coverage and plodding pursuit on WR Joe Jurvecius’s 69-yard TD reception that blew the game open in a 27-10 loss.
