Although I couldn't possibly comment, some might say the riders any team manager picks in his side should not be making mistakes either but they do! That's life isn't it? EVERYONE makes mistakes - even "the best team manager in the country" to use your own definition of him! I'm just hoping speedway never follows the oh-so-ludicrous example being currently shown within top league soccer in the UK when, if anything goes wrong at any club it's deemed all the manager's fault, he gets sacked / paid off and toddles off to await the next offer to come his way leaving another (who was probably blamed and sacked from the manager's/ assistant manager's position at another club in the past following a run of poor results!) to be drafted into the job and hailed as some sort of miracle worker!
Anyway well done to Middlo for his considerable efforts, congrats and good luck to Rosco in the job and with Phil Morris / Neil Vatcher working hard on the development of young British talent, in the look term things look fairly promising to me.
