If there was a question it was answered. Parker was singled out almost the entire off-season as a player who was on the verge of breaking out. The one player that was going to stand out in camp. He did and it was all positive.
Parker showed fans, media, and more importantly his coaches that his change of routine was indeed a positive one. He showed them why he was a first round draft pick only three years ago. For the first time in his NFL career, Parker made it for the start of camp and remained in camp without getting hurt. Knock-on-wood.
Parker finally showed he could use his large frame to seal out opposing defenders (or in this case his own teammates) to shield the ball from them while he positioned himself to make the tough catches. He worked on his route running as well and it showed with him gaining more separation against defenders.
The Dolphins need Parker to continue this progressive change and developement and if it does continue, then yes, DeVante Parker will indeed be the breakout player of 2017.
