I disagree. but I think you could be right. My disagreement is actually predicated in my faith in Porcello to solidify his position in the lower middle of the rotation, E-Rod to be effective once healthy, and actually the growing confidence I have in Stephen Wright who has been a very very pleasant little surprise so far this April.
If we get this version of wright or something like him for most of the season, we're actually good for starting pitching pending what we get out of ERod.
If the rotation looks like:
Price
Erod
Wright
Porcello
Buchholz/Kelly
... where do you put the other starter? much less the guy you're wanting to acquire? You don't get rid of Wright until he proves you should get rid of him, right now Wright is pitching like that #2-3 you wish you had. Kelly is vulnerable, but he's already likely to lose his job when ERod is healthy.
Unless Wright regresses to the mean or someone gets hurt there's no gaps in this rotation that you would be particularly desperate to close. We don't have an elite rotation, but we do have a complete rotation thanks to Stephen Wright. Wright's performance is better news for this franchise than I think people recognize, if he keeps it up, you could be looking at our rotation becoming a strength rather than a weakness, especially if we get good the good version of Buchholz as the season warms up.
