ESPN has decided to keep much of the combine details for insiders only, so there hasn't been alot on Dak and how he is doing at the combine. However, I found this just a few minutes ago on the NFL.com. So I thought I would share it with everyone.
Copied from the NFL.com article, "Day 2 NFL Combine winners and losers"
"Dak Prescott, QB, Mississippi State: The search for a viable option after the first two quarterbacks (Goff and Carson Wentz) makes Prescott an intriguing candidate. He was one of the top performers in passing drills, exhibiting outstanding accuracy, timing, and touch. He consistently put the ball on the mark on intermediate throws and showed a deft touch on vertical passes along the boundary. He also showed impressive footwork, balance, and body control when he dropped back, which shows growth after spending his entire college career operating from the shotgun. Considering Prescott's rock-solid intangibles and his impressive leadership skills, it's quite possible several teams could consider him a worthy candidate early on Day 2."
