PLAYER ANALYSIS
It's hard to stand out as a primary receiver in a triple-option attack, but Koski showed consistent improvement in his play and production over the years. He's durable with adequate straight-line speed and plus ball skills to finish catches in traffic. Teams might view him as an inside/outside option, but his route running and press release have a ways to go. His best shot might be to earn a practice squad nod in order to work on his post-grad receiver's degree.
