Any slim chance Gonzaga's peers had of loosening its chokehold on the WCC title probably disappeared this offseason by the time Mark Few finished restocking the Zags' roster.

Few added several potential impact transfers and one of his best recruiting classes in recent memory to a roster that returns three starters from a 29-win season.

The most significant addition is probably former five-star recruit Kyle Wiltjer, a 6-foot-9 Kentucky transfer hoping for a Kelly Olynyk-esque jump after redshirting last season. Wiltjer, an inside-outside threat with a lethal 3-point shot, should start at power forward and provide a perfect complement to physical 7-footer Przemek Karnowski, who does all his damage with his back to the basket in the paint.

The other key transfer is 6-foot-5 wing Byron Wesley, a three-year starter at USC who averaged a team-high 17.8 points and 6.4 rebounds this past season. Wesley should start in the backcourt alongside returning standouts Kevin Pangos and Gary Bell and potentially shores up a traditional area of weakness for the Zags. Few has developed many skilled big men and quality guards, but Gonzaga has often lacked a small forward with high-major athleticism who is capable of both creating his own shot and defending the opposing team's top perimeter threat.

Though none of Gonzaga's incoming freshmen are likely to start, several could make immediate contributions off the bench.

Slick-passing four-star point guard Josh Perkins likely will spell Pangos or play alongside him, relieving him of ball handling duties the same way David Stockton did in previous years. And 6-foot-11 Domantis Sabonis, the son of former NBA center Arvydas Sabonis, is a polished, skilled forward with high-level experience, having played in Spain's top division last season.

Assuming the newcomers meet expectations and Pangos and Bell avoid the nagging injuries that have hampered them in the past, Gonzaga has a chance to match its exploits of two years ago when it won 30-plus games and earned a No. 1 seed in the NCAA tournament. Of course, that team famously fell to Wichita State in the round of 32, an outcome that added to the Zags' reputation as March underachievers and increased the pressure on future teams to avoid such early-round flame outs.

Of the other upper-echelon teams in the WCC this year, BYU probably has the best chance to capitalize if Gonzaga unexpectedly falters.

Reigning WCC player of the year Tyler Haws highlights an excellent backcourt that also includes versatile Kyle Collinsworth, one of the only players in the nation to lead his team in both rebounds (8.1 per game) and assists (4.6). The question will be whether the Cougars have enough frontcourt talent to replace standout freshman Eric Mika, who left for a two-year Mormon mission. Defensive-minded 7-footer Nate Austin should start at one spot, while the candidates at the other spot include sophomore Luke Worthington, UNLV transfer Jamal Aytes and freshman Isaac Neilson.

The third contender is Saint Mary's, which finished a disappointing 11-7 in league play last season but hopes the combination of all-conference big man Brad Waldow and a few high-major transfers can fuel a bounce-back season. Ex-Minnesota guard Joe Coleman is a 6-4 slashing wing who should start and provide much-needed perimeter scoring, while ex-Stanford point guard Aaron Bright and ex-Washington forward Desmond Simmons also should contribute heavily.
