Hi gutsroy,
I have a pretty hard and fast rule on players changing clubs. If they are a player that has been in the system a decent period, had a chance to show us, and their clubs, what they have, if they have already shown us a SC ESP (Expected Scoring Pattern), then changing clubs, won't change what they give us, from a SC perspective. Basically, if they have had a chance (4 or 5+ seasons, and/or 80+ games), they are not suddenly going to become a better player, by changing clubs. People are always pointing to "better opportunities" at the new club, but we very rarely see it happen with an established player!
This doesn't apply to the 2 players in question, Caldwell and Hately.
Caldwell - M/F - $348,600 - of the 2, he might have the harder task, to be considered a good pick. Essendon have Merrett, Shiel, McGrath and the surprise packet of Parish, who actually had the 2nd most Clearances for Essendon in 2020. None of them are too old, but none of them are A+ grade Midfielders either! That might be harsh on Merrett, but certainly not harsh on the others. Given Essendon have some perceived Mid depth, but not depth of high quality Mid talent, it is possible that there is an opportunity there for Caldwell. He certainly has the opportunity to have some improvement, and could easily force his way into the the top 2 or 3 Mids at the Bombers. He probably wants to go 95+ to be called a win, and 90-94 to be called a draw, as far as a pick goes. To paraphrase
@wogitalia, if he was just $50k cheaper, he'd be a lot easier to pick! The thing is he isn't, and the likes of Ziebell, Impey and Daniher are more than $50k cheaper. That fact combined with not wanting to fill my team with too many $200k-$400k type players, means I'll likely wait and see on Caldwell.
Hately - M - $310,300 - Really has an opportunity. Goes from a strong club to a weak club. B Crouch gone, Sloane (31) getting older, Laird in and out of the Midfield, you then get down to the likes of B Smith and Ben Keays. I don't think Hately has to be brilliant, to push his way into the top 4 of that lot. We didn't get to see a lot of him at GWS, but what we did see, he certainly looked to have potential. Still he probably needs to go 90+ to be a win, and 84-89 to be a draw. I'm not sure Adelaide have the team, or the players to have 3 Mids go say 95+ at the moment, so that is probably a hurdle. I have no doubt he has the potential to push into their top 4 Mids, the question is, is that enough to keep us happy? Too many doubts there for mine, and I hate Stepping Stones in the Midfield, so he's a no from me.
