(WNFL)- The moody Andre Rison, drug convict Johnny Jolly, and bounty scandal target Anthony Hargrove were all given second chances with the Green Bay Packers. Now, GM Ted Thompson is giving the same opportunity to troubled University of Oregon tight end Colt Lyerla. The Packers signed the extremely athletic Lyerla to their 90-man roster yesterday, after he went undrafted this month and then unsigned as a free agent. Last year, the 6-4 Lylerla was suspended for a game and then quit the team. Later, his driver's license was suspended -- and he was arrested for taking cocaine in his car. He also made waves when he tweeted that the Sandy Hook Connecticut school shootings were a conspiracy. Still, Thompson said there are things people can atone for -- and he supports those who sincerely try. In his words, "That's where we're at with Colt." Lyerla stood out at the NFL Combine in February with the tallest vertical leap and the longest broad jump among tight ends -- and the third-best 40-yard-dash. His agent, Vinnie Porter, said a number of pro teams were looking at him as a possible free agent. Porter said he's never seen a hungrier player. In 2012, Lyerla had 25 catches for 392 yards and six touchdowns. Also yesterday, the Packers signed third-round draft pick Khyri Thornton, free agent defensive back Charles Clay, and defensive end Luther Robinson. The team cut tight end Raymond Webber.
