Couldn't agree more. Berman is one of the top 10 (wait...let's double check ESPN's roster...), top 5 talents ESPN has. In fact, I propose a White House petition to bring back, back, back, back, back the Berman/Jackson NFL Primetime.
Great arm strength - throws with outstanding velocity
Puts nice touch on the ball when he has to
Comfortable throwing on the run
Very elusive in the pocket
Impressive physical skill set
Release could be more compact - slight windup but nothing overly detrimental
Very shaky footwork
Lacks experience - one-year starter
Can't read coverage
Comes from zone-read spread offense
Lacks an understanding and maturity of the passing game
Raw prospect and needs a couple years of development
Summary: Jarrett Brown is the ultimate developmental quarterback. He possesses the prototypical physical tools you want in a quarterback, but he lacks basic understandings of a pro-style system. In a quarterback class lacking depth, some team is going to draft Brown anywhere from the late second round to the early fourth round, and try to develop him into a starting quarterback. I think he is a third-round talent, but I wouldn't draft him as a franchise quarterback - he needs serious development on the bench.
Player Comparison: Tarvaris Jackson. Jackson has been a developmental quarterback in Minnesota with elite physical gifts. I think Brown is more accurate, so his career could pan out differently than Jackson's.
