Exactly. How many times have we been teased by a pitcher over the years only to see him end up a pile of mediocre? Started with Jarrett Wright, the benchmark for teases.
Ok, first things first, if you were teased by Jarrett Wright in any real way... that's your own fault. He managed to go 12-10 with an ERA of 4.70 in his best season with the tribe on a team that prolly scored 900 runs in 1998 (edit, my bad, 847). I get the fun of the '97 post season but, he walked out and threw fastballs, which was more fun to watch than Doc Gooden's arm falling off.
Having said that... back to Carrasco. Much like Ubaldo. He's fucking nuts. But they're a different kind of nuts. Ubaldo is the "OMG what if I throw a fastball that doesn't touch the black of the plate and someone hits it 450 feet" nuts while Carrasco is "Why am I fucking with this clown, I should just earhole him" nuts. Sorry, their respective "nuts" lose translation from the Spanish... its much catchier in their native head voices.
Having said that, Ubaldo has a much longer resume (of both nuts and brilliant pitching), I don't know if the Tribe should bring Carrasco back or not, but stuff isn't a problem, never has been and personally, I keep good arms when the price is right. If they feel like they've gotten through to the crazy part.
Now, if the expectation is that he's gonna pitch like a #2 for a whole season, you'll probably be disappointed. But he's 27 there's a calculated risk to be taken. Maybe even by Carrasco.. I'd tell him "Look kid, here's what happened to Ubaldo without Callaway, you don't have that resume and you've got more Santa Muerte thoughts in your head why don't you take a cheap one year deal so you can show you can do something"
