Yeah he seemed to get dismissed by Maddon last year. The only player really blocking him is Schwarber, who the Cubs seem 150% committed too. Now if schwarber comes out pancake flat like he did last year, Happ could take his spot, but I do not see that happening.
Assuming no other changes to the offense this off-season, he will be a part-time player that will produce when called on. This makes him a guy to in daily leagues for cheap, and I would take a late flier on him in weekly leagues in the event there is some injury in the OF or to Baez.
