You have a link confirming Tanev would have signed for cheaper and longer? Or are we just to assume that because some fan on a fan site says he would, that it's fact? Cuz I don't buy it.
As for RJL, if you meant acquisition then say so. Don't expect me to interpret what you mean when you don't say what you intended. Sure Cracknell has been a great signing...but any time a GM signs someone for the farm and he surprises and becomes a contributor to the big club he's going to be one of the best value signings in the GMs tenure. I guess we'll be seeing complaints soon that Benning didn't possess the foresight to sign Cracknell to a multi year deal.
But really your whole point is useless. By your criteria --having to sign someone to acquire them--we've got Vrbata, Cracknell, Miller, Bartkowski and .... ??? Or do the goalposts move so we don't count Tanev's and Webers deals, just the ones you don't like?
