Jennings and pressure situations

AJ seems to do fine in handling pressures towards the end of games usually during final drives to win the game (going back to his start at the bowl game). Looks like his issues are more mental at the beginning of the games and he probably thinks a little too much about not making a mistake. Anybody else feel the same way?
If this is true and if he can ice his nerves, I think we have a more than a decent QB to win the rest of the games.
