You said it yourself. Langdon, Melican, Sir Dane and Aliir. There’s your back line. You have two talls - one who can play loose (Aliir), and two medium-sized defenders - one who can play tall (Sir Dane). That is flexibility. Grundy becomes depth, which ain’t a bad thing at all (albeit would feel wrong seeing Reg in the NEAFL again)
I think that would actually be inflexible
Not much rebound from defense, four guys 190cm or more but only one can play on the key positions
then factor in Smith and McVeigh, pretty slow
Puts a lot of pressure on Melican whos only played about 20 games and had recurrent injuries
Both Rampe and Langdon as 3rd talls is overkill
He's no Grundy replacement and if he comes at the opportunity cost of replenishing the mids with some pace and skill then i feel we have erred
and with all this defensive focused (ie Moore, Langdon, Jonas?) why not wait till after trades before offering Grundy and McVeigh contracts, that would have been flexible
