2013 was a bad draft for most teams and nix's last year. Also we have 4 players from 2014 and 2015 left so looks like the op is trying to make stuff up to push his agenda, im guessing the whaley sucks one.
2014 - 7 picks - sammy , ck , preston brown , and henderson still on team. Richardson and randell johnson were late round picks and didnt work out, cockrell starts for pitt now but rex tried to "sneak him on the practice squad". Pb seemed pretty good also his rookie year until rex came around. Ck obviously is disappointing but he is also starting to play better, hopefully he can transfer his success at lt to rt
2015 - 6 picks - darby, miller, oleary, and lewis still on team. Karlos also looked like a hit until he became fat and lazy and couldnt put the pipe down, steward was another late round pick that didnt pan out. Darby and miller start. oleary has started to contribute. Lewis doesnt seem to be working out but he was also a 7th round pick.
2016 - 7 picks - all 7 on team still
So in whaleys 3 drafts as full gm there are 15 out of 20 picks here. Im guessing that is pretty much in line with other teams
