K. Bryan looks fine to me. Played better comp than McFarland so his highlights aren't as surreal. Seems to have decent vision. Runs well in between the tackles. He doesn't have the acceleration of a Cook, and that may be the biggest knock on him, but his top speed is fast enough. He doesn't break a ton of tackles, but he runs slippery and will run through an arm tackle. As in, he seems to take good angles and naturally avoids big hits when possible. Portis was a natural at that, although Portis obviously is well, Portis, just saying running "slippery" is the comparison here, not comparing the two.
McFarland played against good competition. They played one of the best teams in VA in Oscar Smith, Josh Sweat's HS, they went up to PA to play a playoff team in Harrisburg, they beat McDonough, ranked
#5 in Maryland, a Baltimore power private school, they played Gonzaga in DC, their biggest rival who was ranked
#6 in MD (they play in MD league because DC is DC), they beat St. Johns who was
#2 in MD to win the title and St Johns beat Delray American Heritage 42-9.
