Bulaga may have started 16 games, but he only played 83.6% of offensive snaps so he missed the equivalent of 2.63 games. Plus, in 2018 he only played 72.7% of snaps and two seasons ago (2017) he missed 11 games and he's on the wrong side of 30. And, like others have said, I think would have been difficult for them to sign Bulaga, Clark, and Bakh. I think your last sentence is correct, but for Nijman, not Light. They added Nijman to the active roster at the end of November, so they think highly of him. I think they want him to get one more year as a backup before trusting him to protect Rodgers, thus the signing of Wagner as a stopgap (while technically a 2-year deal, NFL FA contracts are usually for a year longer than they are intended to be for and I doubt he sees year two). I should note that the snap percentages listed are based on what the previous player did last year (rounded to the nearest 5%). So yes, Bulaga did miss some time last year, hence Wagner at 85%. I think Light has some potential. I don't think he will be a starting RT, but an OK backup. I've heard some rumors about trying him at guard, a la Mike Wahle. We seem to have good success at finding guards from tackles. And I'm not sold on Turner. The end of the year, he didn't look like he could block for pass nor run...
