I've been scouting White in the pre-season. He is a super-lock to make the team, no doubt about that.
He is a good route-runner and he is smart to handle signals and communications at the LOS.
He has a very strange and dangerous tendency to "watch the play", this means if he sees the ball in the air or somebody carrying he might just stop flat and watch the play, this is precisely what happened in Tolzien's INT, white stopped his route to watch the action and Tolzien decided to throw the ball where White was supossed to end his path. Epic fail.
Uses his body very well as a shield against hard hits or when falling.
Has some concentration problems he might be "off" for 2 or 3 plays after something important happens like a TD.
The best ability of Myles White is that he can change directions very fast, in short to mid ranged passing downs he can create enough separation in reduced space to convert the 1st down.
I like White, he is better than many #2 WRs in other teams.
