Trajectory means something (barely) when there are more than a couple of points plotted in the player's career to date. You're jumping ahead just a couple of years here.
All I've seen is someone second guessing a pick they didn't like (I suspect you were pounding the table for a 'playmaker' instead at the time) and using that player's injuries which happened after the draft pick as some sort of justification, despite that being impossible to know at the time of the pick. Do you see how that doesn't work?
As for the trades, they wanted a WR and an OL in that round and obviously felt both were worth the cost of acquisition. I don't know that I like the cost either, but no one makes any move like this, while also saying, 'Ooh, but... y'know... what if he gets injured in year 1...?'. Because they don't have time machines, guy. They just don't.
