It's tough to judge because we don't know who'll be managing the team next season or how Jelavic will do in the remaining ten games. If, as appears to be the case, he's a patchy goalscorer then he could end up getting six-eight goals over the next two months and finish with a reasonable total. There's also the imminent departure of Fellaini to consider.
For now I'd start with Anichebe if he's fit. He's not a natural footballer but Jelavic is no Berbatov either, and the fact that Anichebe can't lead the line for ninety minutes means there'll still opportunities for Jelavic off the bench.
If Jelavic continues to struggle throughout the remaining ten games then it could be time to move him on. As much as I'd love having genuine competition up front, recent history shows that it's generally one-out, one-in when it comes to first team strikers at Everton, which probably has something to do with the fact they can't afford to have too many high-earners sat on the bench every week.
Long story short, if Fellaini stays or is replaced by another grock then I'd probably bin Jelavic. I doubt getting decent money for him would be a problem - the good half-season he had will convince a lot of managers to take a punt on him.
