Steve Blake, PG (POR): The Portland Trail Blazers have Jarrett Jack and former first-round pick Sergio Rodriguez. They used another first-round pick on Petteri Koponen this year and also drafted Florida point guard Taurean Green, yet who is running the show? Journeyman Steve Blake. Blake has been starting and playing close to 30 minutes a night for Portland in November and December, which means he should be on rosters. The guy is short for points, but he'll give you 5.5 assists, 2.6 rebounds, 1.2 3-pointers and a steal here and there. The key here is that he's getting minutes. Not many coaches have consistently shown faith in him over the course of a season, which means he has potential for better averages.

Jarrett Jack, PG (POR): The only reason Jarrett Jack is not in the 'sell' category of this blog is because he is in the 'sell' category for the Portland Trail Blazers. Apparently, they are looking to move him because they've soured on his prospects. A trade to the Miami Heat would give Jack a shot in the arm and make him very valuable again. If he doesn't get dealt, though, he's not much more than waiver-wire fodder.

Paul Millsap, F (UTA): With Mehmet Okur expected to be out for a few games, Paul Millsap's minutes and value shoot up. Filling in for Okur on Wednesday night, Millsap finished with 20 points, 13 rebounds, three assists and two blocks. Okur is dealing with a strained trapezius, an injury that could linger according to my google searches. Millsap is a good source of points and rebounds while Okur is out.

Dorrell Wright, F (MIA): Proceed with caution, but Dorrell Wright might become a valuable fantasy player shortly. He already has - over his last three games he's averaged 13 PPG, 10.3 RPG, 2.3 APG, 1.0 SPG and 1.3 BPG. The problem is consistency. Sandwiched in between two amazing games over his last three is a 20-minute, four-point one-rebound effort. In his other two games, he's double-doubled. He's a youngster and is getting his first exposure to serious playing time. The Heat are short on bodies, so he'll likely continue to see minutes. I would pick him up now in case he continues stay hot - if he cools off, you can always drop him.

Martell Webster, G (POR): If you are wondering what the downside of picking Dorrell Wright up can be, Martell Webster is a good example. Webster is a youngster that is also getting his first taste of starting and prolonged playing time, and he has been wildly inconsistent so far. Eschewing last night's two-point effort because of the flu, here are Webster's point totals over December: 25, 9, 4, 3, 17. Webster doesn't offer a whole lot in the way of rebounds, assists, blocks or steals, so if he's not scoring and hitting 3-pointers consistently, then you don't need him. Travis Outlaw's value takes a bump up if he takes over the starting role.
