The article does say the Jets also worked out punters and long snappers but fails to mention any names.
Legursky was an undrafted guard out of Marshall University in 2008 and played for the Steelers during their Superbowl run and then later went in to play with the Bills in 2013. Although he wasn't a terrible player, he's never been more than average,. However PFF did have him down as a minus 11.4 last year which was 64th in the league, but compare that to Winters who was rated at a -27.4, making him the 5th worst guard in the league that took at least 25% of their teams snaps.
Doug is only 28, so he still has plenty left although with the depth we have at the position with Oday showing some really positive signs this pre-season and Dakota Dozier having just been drafted, I have to imagine these work-outs are for emergency situations as Cimini mentions, although the punting ones could have more merit.
Jeff Baca was a 6th round pick out of UCLA. I never saw a great deal of Baca in college and I don't think he saw the field much last year with Minnesota, well worth working out but I wouldn't expect either to sign any-time soon. Now watch them go and sign Legursky today.
