That's the thing... in 2014, Bradley had already gone back to the MLS from Roma, Dempsey was back in the MLS, Jozy was completely useless at Sunderland (not entirely his fault, but his EPL opportunity came... at Sunderland) We had some dudes kicking around Germany, but only an 18 year old Julian Green was on an elite team.
Said differently, in 2014, we had two guys that had any UCL run (2 others that didn't, including Green), and they were at Schalke (Jones) and Anderlicht (Kljestan, who isn't even in this conversation). We had 11 last year, and 11 this year, plus two on Juve who weren't allowed in. There is always the argument that the Euro leagues trust US players more now than in 2014, but that can't explain it all. If you are taking the coaching out of it, and just look at where our players are getting run across Europe, the talent right now, *today* (not their ceiling), is way better than 2014.
Honestly, even Dempsey, who is my favorite player ever, would need to play 9 if he wants to start because I prefer Reyna, Weah and Pulisic over him. I'll give everyone the 2014 GK for now, but ask me again in 2 years.
