That's ever so easy to answer, and really, you should be able to work it out for yourself.
The reason for signing Evans is that he has proven his ability at a high level in domestic and international football. He's played for Premiership team Manchester City in Europe, he's played for the Welsh National team and he's played in the Championship, scoring 10 goals in 28 appearances for Norwich City and earning rave reviews there (their fans wanted to keep him) before joining us - and we all should remember just how good he was for us in his last season - in fact, he wasn't just good - he was phenomenal.
There is absolutely not one jot of doubt about Evan's ability - not a single jot. What there is a lot of doubt about is whether Evans can actually get himself back to a state of fitness that will allow him to play at that level again. Given the time he's spent out of the game and his injury problems since returning at Chesterfield this was always going to be a gamble. BUT, we knew that at the time and we haven't paid big money for him and he's not on big wages. We've simply speculated, in the hope that he might return to full fitness. If doesn't, hey-ho! We've lost nothing because we've signed him for a pittance. If he does - then we've just bagged ourselves the bargain of the century!
I said on here several weeks ago, when people were speculating about who would be in the starting line up (and some were suggesting it would be Evans and Sharp), that Evans would not start to begin with. Go back and check out the conversation if you like, but I said that because Evans had been out for such a long time he would be gently eased back into it. We don't want to thrust him straight back into the intensity of competitive league football until we are sure that he's over the recurring ankle problem. So it will be short cameo appearances, maybe from September onwards, in my opinion.
Now, is there any other doubt you'd like to cast on the wisdom of signing Evans? Because to me, this is all turning out exactly as I expected it to.
