I co-own a team, and this weekend my co-owner and I got into a mini debate over who was more valuable this year: Jason Kidd or Jose Calderon.  My feeling was that Calderon was more valuable, but that Kidd's (who we own) name was bigger so we could trade Kidd for Calderon + an upgrade.  My co-owner's thought was that Kidd is still more valuable, and that with the way our team was set up we couldn't afford to trade him for Calderon even if we got an upgrade.  I saw his logic and backed down, but what do you guys think?  Let's look at the numbers:

Kidd: 10.4 ppg, 8.2 apg, 7.1 rpg, 1.6 3-ptrs, 46|PERCENT| FG, 80|PERCENT| FT, 2.8 spg, .5 bpg, 2.9 TO

Calderon: 13.5 ppg, 9.0 apg, 2.8 rpg, 1.4 3-ptrs, 45|PERCENT| FG, 100|PERCENT| FT, .6 spg, .1 bpg, 1.8 TO

By the numbers, it seems clear that Kidd has some definite advantages (rebounds, steals) whereas Calderon really only has an advantage in turnovers.  But, we have to consider that Kidd normally shoots much worse from the field (hasn't topped 41|PERCENT| in five years) whereas Calderon is a career 50|PERCENT| FG shooter.  Calderon was also scoring much more than Kidd before his hamstring injury caused him to leave his last game early with only four points (and skew down his scoring average).

That raises a second issue: durability.  Calderon has never handled the full-time point guard responsibility for a full year before, and he is already having ouchy injuries which doesn't inspire confidence.  On the other hand, Kidd will be 36 years old before the season ends which is very long-of-the-tooth for a perimeter player. 

I believe that when the season ends Calderon will have his scoring average up over 15 ppg on excellent shooting percentages, whereas Kidd will maintain his commanding lead in rebounds and steals.   I had Calderon and Kidd ranked right next to each other on the cheatsheet before the hamstring injury, and if a draft were held today it would be a tough decision to pick one over the other.  Ultimately, the decision comes down to preference, team need, and gut instinct.  My co-owner and I couldn't afford to lose Kidd's rebounds in our league (he's like having another center), so we decided to hold onto him.  But if I were building a team from the ground up, I think I might lean more towards Calderon's scoring, efficiency, and youth as the easier player to build around for roto teams.  What do you think?
