First time I've watched the full hudl highlight reel from his 2015 season... my goodness, he looks awesome. Obvious speed and agility... but he also shows an ability to make tough contested catches. I fully expect him to make a significant, immediate impact this season.
I predict Jonah is going to be a better version of Blackmon. I see better separation speed and YAC agility here:
