Waterloo is a darkhorse to challenge for first or second place, with a veteran team which returns 81% of its scoring from 2008-09. They went out to the West Coast and stayed within single digits of UBC in preseason despite not having a full lineup, and as Mark Wacyk has pointed out by way of assistant coach Curtis Dauber, beat Toronto without the services of McIntyre and guard Jordan Hannah.
Defensive rebounding was an issue last season, which is surprising considering the emergence of the 6-foot-9 Hayes at centre. The 6-7 Frisby is a great glue guy who can defend anyone one through five. Waterloo has a chance to make some noise in what is arguably the deepest division in Canada.
