I don't think it's good for his personal development as a player simply because he lost out on the ability to play against the best in the world (assuming Roma qualifies for Champions League) but it's good for the league, that I agree.
Even with De Rossi, Nainngolan, Pjanic and Strootman, Bradley would have gotten some decent playing time next year. He actually played quite a bit this year when Totti was hurt for the month of November and Pjanic would be pushed up as a false 9 and Bradley would play in his spot . He did not do well in that role simply because he's not meant to be a regista but it still showed that Garcia had a lot of faith in him.
