Editor's note: ESPN.com's Andy Katz takes a season-by-season look at the Three-Year Plan.

Omar Cook should be the norm, not Stephon Marbury or Sharif Abdur-Rahim. Cook's inability to get into the first round and to hope and wait someone would pick him up (it ended up being Dallas for now) should be a sign to all freshmen who want to bolt after one season.

If they're not a lock for the lottery, then the gamble might not be worth risking the money and the disadvantages on a player's game. DerMarr Johnson is finding this out and, so too, might Gerald Wallace.

	Dwyane Wade, a redshirt freshman at Marquette, says freshmen have too much to learn in college to even think about leaving after just one season.

If the decision is to be a three-year guy, then the freshman season is all about getting the feel for the game, and making the adjustments. The freshman season can be about making mistakes, and learning. No one expects a player to be able to come in, show he can score, defend and pass all within the first few months of his college career.

Dajuan Wagner is an exception and is likely gone. But he's not been expected to stay for two, let alone three. Memphis coach John Calipari understood that when he recruited Wagner. He can ride him to the NCAA Tournament and hope that there's a chance that he could stay longer.

"The first year is all about potential," Missouri junior guard Kareem Rush said. "Dajuan Wagner could leave after one year, but that's not going to happen too often."

The buzz on Marquette's Dwyane Wade is he could be a one-year-and-out player. NBA scouts are checking him out just in case. Wade is a bit different because he sat out last season as a partial qualifier. He was able to practice, but not play. He's already been in school three semesters and if he did bolt it would be like a sophomore leaving.

But Wade understands how much more he has to learn and needed at least the one season of practice and another of playing.

"I'm so much more ready now to contribute than I was a year ago," said Wade, whose production as a combo guard led the Eagles to their torrid start. "I learned a lot while I was sitting out. I learned the ins and outs of the game, stuff I wouldn't have been able to use after one year."

Wade is savvy to know that staying in school has made him a smarter player and given him a more realistic appraisal of his game. He said freshmen too often think they can come in and take over a game -- and unlike Wagner, at times Cook, and definitely Abdur-Rahim and Marbury -- that doesn't happen too often. Wade might not have been able to do what he's doing now had he been eligible as a freshman.

"You can't take over games all the time as a freshman, you can't," Wade said. "Look, the money will be there and it's clear that staying another year is better for you. Just look at Jason Williams and what that has done for him."

But the learning curve is picking up. Players are more prepared to contribute as freshman because of the amount of playing time against elite players in the previous summers. The defections to the NBA and the fewer scholarships means there are more minutes for freshmen.

"Nowadays, everyone learns real fast and some guys think they learn too fast that they know everything," said Wade, speaking like someone who will likely stick around for at least another season. "To have a guy for three years is the best, because usually that means you're better than anyone else. That's why Duke is so successful because they've got three-year guys."
