Milera had some game-breaking performances at senior SANFL level in 2015. If you watched him that year, you'd argue he might have had some of the highest star power, and especially 'wow factor' in the draft with his sublime skills. Caldwell I'll admit was, in my opinion, a more game-breaking midfielder than Jones, but it's hard to say Caldwell was riskier than Jones due to injuries, when in fact Jones had some of his own serious ankle problems in the two years leading up to the draftI'm more specifically talking about drafting Milera over Charlie Curnow and Jones over Caldwell, who were the very next picks in each of those drafts.
Milera has good qualities, but we passed over a player who in my opinion has clear top-line star power. Unfortunately Curnow ended up injury prone, but I don't think he is the sort of character we were after.
In 2018 a lot of draft watchers were calling Caldwell the superior, better skilled footballer, but had risks due to injury issues. Jones is your classic safe pick, comes from a good family, has pace as a physical trait, etc. We chose to pass on the risky (allegedly) higher skilled midfielder for the talented but safer pick.
I don't think we necessarily have gotten these calls wrong on every occasion, but in my opinion we do have a "type" under Hamish which is on the safer end of the scale.
Personally, I'm not sure we have a 'type' - our first-rounders have seen us select both high-talent types as well as some 'safer' picks, as you say. IIRC Hamish said he would've selected Rayner at 1 in 2017, even as being seen as one of the more 'boom or bust' types out of that top group of players selected (Brayshaw, Dow, LDU, Cerra). We've carved out a pretty even balance I reckon, and the reality is (with any high selection), sometimes they work out, sometimes they don't
