Very little chance he is trading Cirelli, as contending teams don't trade their quality 2C's when they don't have any reason to. The team seems to have made it pretty clear that Cirelli is part of the core F group, and removing quality talent from a group that needs a bit more depth makes little sense. JBB certainly isn't moving him for futures given Tampa's current position, and there's little reason to make a hockey trade when you're not going to be upgrading at the position, only making a lateral move at 2C or weakening C depth to address some other position.
Adding a 2RW such as Bjorkstrand makes a lot of sense now, as he's in his prime and will help for the duration of the remaining g window. My hope is that JBB adds the 2RW+a middle 6 winger with "grit" at the tdl, preferably players that have some term or seem likely to extend with Tampa. As far as defense, the top 4 still seems set for the next 1 or 2 seasons, but if he can find a top 4 D in the summer to help with the eventual need to replace Hedman/McD, all the better.
