Kendall Wright is hoping that better technique and route running will provide better results in 2015. I don't see an instance where he can't get better by improving those things. His ability to play inside and out and his general YAC ability and ability to catch everything got him to be drafted by us in the first round, so improving the technical side of his game should allow him to become really really good.
The entire offense, Mariota included had a bad day offensively on Monday. However, silver lining is that the defense had a great day of practice.
