Don't mix your bias toward larger players with good development practices.
The Habs have drafted players of various sizes, including smaller guys like Farrell, Mesar, Simoneau and Kidney and even Fowler and Beck to a degree, and must include all of them in their development plan.
Also, every AHL team has vets. Without vets around them, the young guys do not progress well or learn to compete better.
Not all the vets are "small" ABB, RHP and Gignac are, and we don't know if all three will be back.
But Dauphin, Condotta, Hayes, Jacobs, Hoefenmayer, Lindstrom and Arseneau are definitely not small. Some of them will be back, I'm sure.
