It's a proven goalscorer we need, and they are rare but not impossible to get if you are bold and pay a lot of money, it's the only way unless you can develop your own, which so far we haven't. Most but not all the Conference level ones have been snapped up, they are the ones most likely to want to prove themselves in League 2 by sticking it into the net. Don't know enough about MacLean to make any rreal comment, except that if it's true he got only 6 goals in 54 games then he simply cannot be the one we need! A striker scores goals, at least 1 every 2 games. Forwards are a different matter and should not be confused with strikers.
As I said Steve, he was playing in the championship for a struggling side and had a few niggling injuries. His record at League 1 and League 2 level is fantastic. It's like comparing Jermaine Beckfords form from his time at Leeds to his first season in the Premiership with Everton. It doesn't make him a bad player but some players cannot make the step up. For our level I think he'd score a hat full.
