From that article:
But anyways, there you have it, my plea to avoid overestimating value based on small sample sizes. Waiting until the 50 game mark might be too much to ask, but at least get past 20 games before you claim having advanced knowledge about the causes of a player’s performance this season.
The only thing I claimed was that if you have an empty roster spot or a droppable bum he's worth a look; if anything keep tabs on him to see if he keeps it up. I don't even own the guy in either of my leagues,I'm not trying to pimp has my "OMG grab him now, '09s Voltron/Cliff Lee!" sleeper by any means. The only comparison I made was Gavin Floyd and that's just because he was a mid twenties pitcher that finally put it together, I'm not saying Davies will do the same but it's not impossible. As you know, you have to take a shot at an unproven player whose shown glimpses of potential every now and then if you want to keep an edge over your competition. If you wait 50 games for a player to prove that they're for real (and they do), they'll be long gone.
One thing I WILL claim is that Davies had a great September and carried that momentum into his first start
