I don't really see any reason to keep Bennett around. Hornqvist and Kessel will be around a while, Perron might be also. Bonino might be moved to the LW for the top 6. There's no room for Bennett even if he does pan out.
I agree with your view but Bonino has gone on record saying that he feels much more comfortable playing center and sees himself thriving as their 3rd line centerman.
Plots, Kunitz and Fehr can always step into the 2nd line LW if need be...
