Salvation
Damnation
I feel like I've not seen enough of Carroll if people are saying this because he's never looked to have half the talent Rooney had. His goal record's fantastic but it's too early to judge just how prolific he is as we've seen others match his output initially but eventually show their true quality, but even considering it is a true reflection of his prowess there has to be more to his game than that to be compared to Rooney, who was at that point recognised as a guaranteed star in the making.
His variety of goals is promising if not outstanding - two outside the box finishes, four headers (three set pieces), and then 5 inside the box finishes. Aside of that I don't really see any quality close to that level, his touch is reasonably tidy, he's got a decent strike from range and he's a more than competent passer but I've not seen a lot more than that. Granted there's not a lot of time to show off your skill in the build-up in such a direct and powerful team, but that works the other way in the sense that he may not be as suited to the more sophisticated and possession-dominant attacking football that you expect at a top club.
We've seen it perfectly demonstrated by Drogba how damaging raw physicality can be, but there's so much more to his game than I've yet seen from Carroll (even considering he continues his steep improvement).
I'm inclined to say this will turn out to be a good buy in years to come. Caroll is technically better than what most give him credit for. He can run at players, and has a very good touch on him. Let's say he's akin more towards Drogba than Heskey. He isn't anywhere close to how good a teenage Rooney was, though. But few, if any, are. Eventually, as it was with Rooney, injuries and how he progresses over the years will be vital.
Obviously, it is a gamble. But one which seems more likely to pay off. Even if it doesn't work out, he should have a fairly decent resale value due to his nationality.
