The Hammer's front man has been prevented from reaching his potential because of consistent injury problems.
Horrendous luck with injuries has hampered his progress over the past three years, however, and has seen his career stagnate. Nine international caps is something to be proud of, but it could have been so much more. However, at 27 years old, Carroll still has a lot to offer.
He is loved by the Hammers faithful for his tireless work-rate and never-say-die attitude. His goalscoring record is typical of someone who puts extra work in for the team rather than his own personal glory. His return of 18 goals in 79 appearances doesn't tell the whole story.
Following West Ham's progression to the FA Cup Quarter Final, Liverpool fans bemoaned the fact he was playing in Claret and Blue rather than wearing their famous red strip. Instead they had to endure Christian Benteke's tepid display. Their two performances that night were like chalk and cheese.
With Carroll in the side, The Hammers always seem more dangerous, and more direct, which suits their pacey wingers. It is hard to believe that he was being linked with a move away from Upton Park in January, and even stranger that West Ham are now being linked with the aforementioned Benteke.
Carroll offers a great option when he leads the line. He rarely loses an aerial dual, and is a real asset from corners and free-kicks. His defensive contributions cannot be over-looked either, where he can be regularly seen winning headers in his own box.
With his fantastic ball retention, he links up the play and allows Manuel Lanzini and Dimitri Payet to become more involved in the game.
His inclusion in the side, however, seems to depend on West Ham's opposition on the day. If he can get a run of games under his belt though, he is the kind of player Slaven Bilic will find hard to leave out.
With a strong finish to the season, it is not entirely out of the question he could be called up to the England squad for the Euro's.
West Ham should continue to show faith in their striker, because as Liverpool fans have shown, you don't know what you've got until it's gone.
