Simpkin, Siposs etc were given contract extensions I'm pretty sure Wright and Saunders, Curren etc were also given extensions. I know we have to spend the cap up but I think we probably got a bit overzealous with the contracts. Some were shitty Lee was signed up to a longer contract than he deserved too. Some of these guys will make the cut but we locked a few a way we didn't probably need to rush into. Cripps and Lynch might have made us a bit nervous.
There's a few things to consider...
Firstly, some of our rookies such as Weller would have to be upgraded due to form / potential. Same with Eli.
Secondly, I suspect that the others were given extensions because we simply could not flush them all out in one draft.
Had we delisted 3 or 4 more players rather than give them 1 year extensions, who would we replace them with? Picks in the 100's? Given the talent pool, that would be silly.
So I reckon we have held on to a few because we had to rather than because we wanted to.
