Caps have 3.3 in cap space currently. Chicky is a +4.5m compared to this year, so all else being even you need to free up 1.2m next year and the Cap is going up, so i don't think it will be terrible.
Backy and Oshie come off next year (although they had no cap impact this year really).
I expect the Caps will let Mangi walk at 5.8m...thats alot of cap space right there.. let Mangi walk, pop Milano back (1.9m) in and you still have 2.5 or so in Cap space next year without an increase in cap.
Mangi, Dowd, Raddysh, Eller & Beauvillier are all FA next year. If you sign all but Mangi, I think you still have some cap space left.
We shall see.
