I don't know if it's more than off set. I've yet to hear a theory that fully explains why the scouting broke down so badly with Olivera.
After trading for him Hart said "And I think John accurately portrayed the Olivera deal. There’s a bit of an unknown, but I think with the eyes that we had on – Roy Clark, Gordon Blakeley, Fredi (Gonzalez) saw him – we had multiple, multiple looks at the guy, and knowing the market, that if this guy hits like he’s hit before and is the player that our guys have said that he is, then we’ve ended up making a nice deal."
So this wasn't a case of just one scout falling in love with the guy. We had multiple people raving about Olivera. But when we actually get to see him even the casual fan can see the huge flaws in his game.
I still don't understand how we were so wrong on this guy. The only thing I can think of is that they watched video of him playing in Cuba and just completely forgot that the guy on film was in his prime and the guy they were signing was aging and hadn't played in a couple years. That's not a good look for the scouting department.
