Now l may have my head bitten off but have a open mind for a second

Now l can't see Fev at the club in 3 years time, he wants a crack in the NFL. I could be wrong. But, l think our best chance of winning the premiership is in the next 2 -3 years. Beyond that it may be hard to get good draft picks.
The way l see it, we are only 1 key backman away from a premiership and one or two forwards away from the premiership.
Now l was thinking that if we could snare a couple decent forwards and backman near the end of their career for not much, then we would go very close to a premiership. Clubs offload players just because they are 28-30 with a couple good years left in them, which you have shane crawfords, alastair lynches, rob harveys, craig bradleys all producing good footy in their 30s
I know i will get abused for this, but this is an example!!. If we could pick up a Tarrant for basically nothing, he can play on tall forwards fairly well and still has a good year or two left in him. This would mean Waite can play CHF and means we finally have a spine in the team with no gaps.
We could also pick up russell robertson for basically nothing, and he would be pretty handy as a small forward. I saw him the last two games of the season and he looks good.
Just those two additions would mean Kruzer/Warnock would be the only rucks. No Cloke or Hampson in. (Plus)
Waite could play CHF, meaning it would be hard to double FEV (PLUS)
Robbo is pretty quick, good mark and kick and can play the porplyzia role and take pressue of FEV (Plus)
A Tarrant would provide a extra tall in the backline in a key position, which when we have injuries we wont have no other options like Brisbane exposed. (Plus)
Blues forward line has options, not predictable (Plus)
I could handle a Forwardline like this: Fev, Waite, Robbo, Yarran, Betts, with Kruze drifting in there.
And a Backline with: Jamo, Bower, Tbird, armfield etc, with Tarrant playing more as an emergency, depending on matchups.
We can keep getting draft picks and waiting 4-5 years for them to develop, or we can patch up a couple spots with the intention of winning a premiership in the next two-three years.
What you think?
