I agree if this is actually on the board its better. Contract baggage in both but I think Collins upside is best of this bunch.
Toppin feels like more of a prospect, but he's not that younger and we know Collins has reached a much higher level than he's at right now. If I had to bet on who ends up the better player definitely lean towards Collins. But Collins may just end up perpetually rotting in ATL by the looks of things.
Contract situation is not great for Collins, but it's a matter of opportunity cost and I don't think it's that big of a burden. If you're really banking on FA in summer 25 Collins might get in the way of your plans....but for me personally the concern is not enough to prevent me from getting John Collins.
