re: how long can JL maintain a good attitude ?

Oh I agree I think the failures of both QBs over past three years hangs largely on the heads of the coaches, for one not adequately preparing them before throwing them to the wolves, two not calling proper plays that play to each's strengths while helping offset their weaknesses, three predictable play calling and repeatedly calling plays that didn't work the first 20 times, and four not developing the players without first destroying any confidence the player or the fans have in their abilities.
