Thing about KC was that he was a tough guy to follow on this board because often times he was unable to post until about 4 p.m. PST so many times the east coast games were virtually unplayable if you were truly trying to tail somebody. Obviously this is his first season with a service so plays will have to be made early in the day so it is impossible to tell how that will affect his results.
Fletcher ran a very successful baseball service last year, but you would have to ask him where it is documented if you want to see the full records. He's forgotten more about the actual playing and psychology of the game of baseball than most folks ever knew (one of his favorite quotes

). He does play a decent number of dogs but his big plays will be faves so you better be willing to take the hit on faves if you play with him.
I think gsp is a smart baseball handicapper who, in my opinion, relies too much on umpire data. Just my opinion. Actually, gsp is smart at just about every sport. I don't know if he has ever documented his results but I swear when this guy sees something it is usually right on target.
Jack had a great season in baseball last year and obivously he knows what he's doing. I know IE knows his stuff as well because I can credit basically 100% of my success in baseball to the knowledge I have learned from IE.
Meestermike had a great baseball season last year, his first on this board. He plays way too many plays for my nerves, but if you love action, try him out. He may be starting a service, though.
ndnfan is starting a service and I would definitely stay away from anyone who is entering their first ever season of selling picks. I am not going to mention the names of the folks who have failed and posted results far worse in their first service season than they had ever publicly posted before, but just trust me on that one. Running a service is a whole different animal than just posting plays in a free forum and there is no way I would trust my money with someone who is just starting up with no documented service record. I am sure that ndnfan, who by all indications is a good handicapper and a nice guy, will like me a whole lot less for writing that, but I have to be honest about things like that.
Nolan will surely have plenty of baseball angles. If you play totals he will probably post some decent winners. I am sure there are others out there as well that I have forgotten about by accident and many more that I am "forgetting" to mention on purpose because I don't want to start a flame war by publicly noting my honest opinion of their handicapping prowess.
One thing I want to qualify in all of this is that I DO NOT recommend blindly tailing anyone unless you are betting relative peanuts. Learn to handicap yourself if you are going to bet any kind of significant amount of money. Of course there are exceptions, but that is generally a pretty good rule.
