Not certain as to what exactly gets this deal done but this is the foundation. Replaces Ceci with a player that can skate & defend well off the rush (at the cost of size) & frees up significant cap space (both Ceci's hit and whatever of Brown's bonuses won't count as overage due to opening space this year). The 4th is an effort to maintain some semblance of a prospect pool.

The 1st is the primary value for NSH, but Ceci is still an NHL player and would likely return at least a 3rd or 4th with retention at the deadline next year.

What might be needed to complete this trade or is this enough?

5th to a third team for extra retention
