All I can say is welcome to the forum. You will begin to notice who here to simply ignore soon.
This forum is a place where people look at 4-5 games worth of stats, make some bold statements then choose other stats to defend these positions. With Sanchez it started last year, so people will simply continue until they are right (and so it's boring to keep saying it over and over) or they are proven clearly wrong (i.e. 3-4 great years).
Edit: If you think it's bad when they predict someone to be bad, wait until they predict someone to be good and wait 3-4 years for him to be bad, then somehow blame the Jays for him being bad. Honestly if you're here for deep analysis of baseball you may be better simply listening to the Jays' broadcasters
