The Arizona Wildcats faced the nation's best wide receiver, Oklahoma State's Justin Blackmon, when the teams met two weeks ago in Stillwater, Okla.

Last week brought the presumptive No. 1 pick in next spring's NFL draft, Stanford quarterback Andrew Luck, to Tucson.

Now, the Wildcats must prepare for Oregon's LaMichael James. In three games, James - who, like Luck, was a Heisman Trophy finalist a year ago - has rushed for 325 yards and five touchdowns.

Three players, all considered the best in the nation at their positions. All in three weeks.

"The player in me would have relished the chance to compete with these guys here - but I'm glad I'm not," UA defensive tackles coach Joe Salave'a said with a laugh. "It's one thing to try to get ready for one guy, but to account for the others?"

As scary as it seems, James - who travels to Tucson for Saturday's 7:15 p.m. game at Arizona Stadium - might be the best player Arizona faces all year.

The Ducks tailback certainly has the most impressive résumé. In two-plus seasons as a starter, James has rushed for 3,602 yards and 40 touchdowns. He has caught 520 yards' worth of passes and four scores.

James touched the ball just 13 times in last week's 56-7 win over Missouri State but put up 231 yards of total offense - a 17.8 yards-per-play average. He ran 12 times for 204 yards and caught one pass for 27 yards.

But it's James' intangibles, and not necessarily his numbers, that make him so hard to stop. UA linebacker Paul Vassallo said defenders can fill gaps at the line of scrimmage and still miss James as he runs by; the Ducks' splits are so wide, and their tailback is so fast, that it's easy to look silly.

"You might still be in your gap, but the way they block everything, the gap is so big that he may still fit in your gap," Vassallo said. "That's something that's so different you definitely have to be gap-sound."

Tim Kish, the UA's defensive coordinator, called James "an awesome back."

"If he's not the best, I don't know where you'd categorize him. He's damn close," Kish said.

Yet, among Arizona's players and coaches, James is merely the latest great player to cross their paths this year. Blackmon paced the Cowboys to a 37-14 in over the Wildcats, and Luck delivered on the way to a 34-10 victory in Tucson a week ago.

Still, the Wildcats aren't backing down.

Defensive tackle Sione Tuihalamaka said the challenging September "makes me excited, and makes me want to work harder toward our goal."

The UA figures it can only improve, even if it falls short in the effort.

"It's hard for other people to imagine, but for our young guys to get this kind of competition and experience, it's priceless," Salave'a said. "We've just got to make sure that we go into each contest with an attitude that we have a chance. And we do have a chance. We just have to make sure we're sound in what we do."
