Lannan's on the edge of losing it mentally. He knows the Nats placing him in the number 1 slot is a joke and seeing him going up against the other "real" number 1's and having his lunch handed to him each and every time is wearing him down. He's really suited as a 4 and whether he's around when the Nats start fielding a real team is a question mark because some of these guys are just fodder and will fall by the wayside as we all wait for the draft picks to mature and move up.
Which is why you get a veteran to take the pounding. That's what Odalis Perez brought to the table.
