In a keeper league, would you rather have Chris Bosh or Dwight Howard? Keep up the great work.
-- Eric

This is a tough one because both players are young and have tremendous upside. The downfall for Howard is that he was drafted right out of high school and needs a lot of fine tuning. Bosh didn't play much in college either, leaving early, but he did at least get some structure under his belt. I've always liked big-bodied players in the NBA, especially at the forward and center positions. Howard is bigger and much more physical. His shots will come closer to the rim and therefore, his FG percentage should be higher throughout his career. He's already averaging a double-double. Both players hit nearly the same amount from the line and each is turning it over just over two times per game. I like Howard's shot blocking ability a little more, and with the right coaching, he'll average more steals and assists per game. I think in the long run, Howard would be my guy.

I need assists but also field-goal percentage. Should I drop Tony Parker and pick up Brevin Knight?
-- Sam

Depending on how badly you need assists, I'm not sure this is such a good move. Parker dominates Knight in nearly every other staitistical category and I'm not sure that just adding a few assists per game is worth losing everywhere else. Knight's FG percentage will continue to be dismal for two reasons: 1) He's not that great of a jump-shooter anyhow. 2) His team stinks. Plus, for the rest of the way, I trust the guys that Parker will be dishing the ball to more than I trust the guys Knight will be giving it up to. Tony Parker will continue to score, continue to dish the ball, and continue to shoot near 50 percent. I think I'd stay put.

You wrote in your January 12 Mailbag that you don't like giving up two players for one. Could you explain?
-- Everett W.

Sure. I've always been a sucker for depth. For some reason, my fantasy teams ALWAYS seem to lose players, no matter what sport I play. In fact, it got so bad four years ago that I call all my fantasy teams "The Injury Bugs." Only in very rare cases do I allow myself to trade two players (or more) for one. As soon as I do, I know someone is going to get hurt. Plus, because of hot streaks and cold streaks, it's sometimes better to have a choice between two players rather than having to stick with one guy. This isn't something that everyone necessarily believes in, it's just something I have lived by for years and it's been quite successful. Hope that helps.

Who would you rather have, Jalen Rose or Donyell Marshall? Both are inconsistent.
-- Howie

That's kind of an open-ended question. It really depends on what you are lacking, in terms of stats, and how deep you are forward. In some leagues, Rose actually qualifies as a guard, so this could make your decision a little more taxing. If you purely need scoring, then I think it's a no-brainer... Rose is your man. However, I have a feeling you need more than scoring. Marshall will grab more boards and block more shots per game than Rose will. He also steals more balls per game and doesn't turn it over nearly as much. In terms of FG and FT percentage, both are about the same so there is no real advantage either way. Rose is simply too inconsistent for my taste; therefore, I'd lean to Marshall on this one.

I give Chris Webber and Jeff McInnis I get Jamal Crawford, Troy Murphy and Donyell Marshall. Ten- team roto, nine categories. Who wins? I need help in 3's and steals. The guy is obviously trying to up his FG percentage. Am I getting enough for Webber and McInnis or should I hold out to get a real superstar for Webber?
-- NBStow

I'm still not sure that Webber is fully healthy and I can't be certain that he won't miss significant time in the coming weeks with another injury. Webber's numbers are mostly ALL below his career averages. The only places he's shown improvement this year is at the free throw line and in the assist department. Other than that, everything is down a little or a bunch. I would actually be more hesitant to lose McInnis than Webber, as crazy as that sounds. Webber just scares me to death when it comes to injury whereas McInnis is fairly dependable. The fact that Crawford is now back from injury is definitely a plus. He was really starting to become dependable before his injury. In his first game back Monday, he was a bit rusty missing all 7 of his three point attempts and hitting just 4 of 14 shots total. Knowing that his minutes will probably be down a bit, I'm not sure I can suggest making this move... even as bad as Webber scares me.

I just read that Steve Nash injured his back in practice. If this becomes a lot of baby injuries that keep him out, then Amare Stoudemire's value will be shot. I already offered Amare for Dirk Nowitzki straight up, just so that he knows I want him. I'm waiting for counter-offers. I'm in first (12 points) in free throws, assists and steals, with 11 points in FG percentage, 10 points in 3-pointers and eight points in rebounds and blocks.
-- Shaqzilla

It appears you are doing well without making a move. Don't get me wrong, I like what Dirk brings to the table. He's been consistent for three straight years and there's no reason to think he won't continue his fantastic fantasy numbers. But, Stoudemire is putting up monster numbers too and is playing on the hottest team in the NBA. I really doubt his numbers will drop much with Nash on the shelf. Remember, Joe Johnson is still a pretty solid player and led the team in assists last season. Nash or no Nash, this is still a pretty solid unit and Johnson will fill in nicely. The only concern for you would be Stoudemire's injury from last year. Will it creep up this season again? Well, so far so good. If it's not broke, don't fix it. I think I'd stay put.
