I did a quick google on the writer to determine whether he either carries any preconceived biases or tends to shoot from the hip more so than the head, but found evidence of neither. So concluding that this is an objective report, I have to take his observations seriously.
However, few expect a skill player like QB or WR to have refined their pro skillset by the 3rd game so it's kind of harsh to put any such labels on Jake either. He is gonna have to refine his pass blocking instincts and abilities before Henne ascends to the starting position, but I'm confident he can be coached up to do so.
I believe this was one of Hudson Houck's strong suits and do sort of regret that the Triumverate was so quick to dismiss him as part of the Old Guard. The fact that Jake is a man among men (Seymour) in what's now the most important aspect of his game, is more than encouraging - it's heady!
