dermie used a great analogy during grand final week with regards to fev...
gary ablett senior played at hawthorn during his first yr of footy and a variety of things didnt go to plan during that time. obviously the hawks were on the verge of having a great side as they virtually had all the pieces in place bar a few. they were aware of what a precocious talent he was but decided to move him on due to him not doing things the way things were being done at hawthorn, allan jeans was tough like that. they sent him packing as they thought it would be BEST FOR THE CLUB that he was no longer there.
obviously gary senior went on to have a sensational career and became arguably the best footballer to ever lace em up... but most importantly, never won a flag. hawthorn on the other hand went on to play in 7 consecutive grand finals and win 5 premierships over the next 10 or so years.
i believe carlton need to take that same leap of faith with fev and trade him while his value is very high. if he comes back to carlton and has a crap season or is injured for the whole year, his value will drop and the blues will kick themselves for not doing it... while it may not seem like it now, it happens everywhere where someone else steps up and shows some leadership or goalkicking or whatever other qualities that you may not have been previously aware of based on lack of opportunity... where there is one player excelling (ie while the fev show exists), there are always 1 or 2 others waiting in the wings for their opportunity
the last thing they want to do is look back wondering, what if???
