Hewett was a Free Agent and Sydney could not afford to keep him.Hewett wanted out and Sydney let him go for a small contract. Dow hasn’t shown as much as Flanders has and is two years older. Kennedy was rookie listed last year so I imagine teams would’ve been able to get him if they rated him.
Flanders will gain more interest then any of those guys have and for good reason.
His contract is 4 x 450 (not exactly 'small'), they were unable to match and took the band 4 compo.
Kennedy never wanted to leave Carlton.
Flanders may well gain more interest from other clubs. But a lot of that interest will be due to him being out of contract, and not having got a go until Dew was sacked.
