The exaggeration is strong all around.
The majority don't think he's a complete tire fire. He has tremendous stuff but s*** control and command... So his wonderful raw potential isn't being realized. On the other hand, he does show flashes of brilliance (first three innings today) which seduce the Sanchez lovers into believing he will become what many hope he can be.
The truth is that Sanchez is Jekyll and Hyde. He's Forrest Gump's box of chocolate. He is a marvel in one inning, and a dumpster fire in the next.
