Here are Lannan's numbers since 2008 if you take out his pre-minor stint from last year.
89 GS
536.2 IP (6.03 IP/start)
3.79 ERA
4.63 FIP
3.14 BB/9
5.00 K/9
0.99 HR/9
That seems like a decent sample size to me to compared to a bad 14 games in 2010.
It is possible that Lannan was hurting for that set of games and if that's the case, I suppose it would be fair to cut out those bad games and look at this set of stats. Otherwise, I think you have to include them and just look at Lannan as the guy he's been for a while now - an ML caliber #4ish starter. No better and no worse.
