Hislop and Thomson are for the tip. Not good enough at successful teams like Bombers and Port so eff knows why we think they will do better at Punt Road.
Can you tell me exactly when the Bombers were last "successful"
The finished below us in 2008 and when did they last play finals regularly
I would think it was before Tom Hislop time 
And let's not hang poor Adam Thomson out to dry either. 4 seasons at a club that finished 8th, 12th, 2nd (grossly over-achieved eg Richmond 2001) and 13th. Yep, a real successful club for the period he was there.
The success or otherwise of the club at the time is much less relevant than the 'fit' of a player to the club. The player might not get on with some team mates, might not react positively to the coaching staff, might not be mature enough yet, might not like the city they live in, might have an ego that only a sacking can cure, who knows whatever the reason - the point is there are many, many examples of players not succeeding until they reach their second club so to make such a broad generalization as "Hislop and Thomson are for the tip" at this point of their careers and before they have even pulled on the new jumper just smacks of ignorance and immaturity.
