1. Bledsoe seems injury prone, and I think he has had part of his meniscus removed. I think that Wade's issues with his knee have to do with missing meniscus
2. Bledsoe is a bit undersized at 6' 0.25" barefoot.
There is a 3.5 year age difference between Dragic and Bledsoe, but the Total Career Minutes difference is about 5,000 minutes (10,600 to 5,500). That's about 1.5-2.0 seasons or so.
Dragic's ORTG/DRTG from BBall Ref last year was 119/109 (+9). Bledsoe's was 110/106 (+4). Their WS/48 were .186 (GD) to .140 (EB).
Dragic is the bigger and better player, at least at this time. My guess is he will have less injury issues going forward, also, as compared with the shorter Bledsoe.
Careful with individual Drtg, not really a stat that says too much. At it's most basic, it is team defensive rating plus defensive stats (defensive rebounds, steals, blocks), it isn't the teams Drtg when the player is on which I think is what most people believe it represents. If you want to find that, look at on/off numbers. Not sure there's much real value to individual Drtg.
Good point. I did know that it was "individual DRTG" and that is why I used it here, because I just wanted to get some kind of ballpark "feel" for where GD and EB might be at (in Individual ORTG/DRTG).
All the numbers show Bledsoe is the better defender.
Individual DRTG (lower is better)GD --> 109
EB ---> 106
Defensive xRAPM (larger positive number is better)GD --> -0.9
EB ---> +3.0
Defensive points per 100 possessions (On - Off) (larger negative number is better)GD --> +0.6
EB ---> -6.2

The difference in the overall effectiveness of the players comes because the gap between Dragic's On/Off offense and Bledsoe's On/Off offense is larger than the gap between Bledsoe's On/Off defense and Dragic's On/Off defense (which is the point I was trying to make with the individual ORTG/DRTG stuff I first put in).
As Dragic has a negative xRAPM for defense (2013-14), so Bledsoe has a negative xRAPM for offense (2013-14). The numbers work out such that, according to 82games, here are the Net Points Per 100 Possessions for each player for the 2013-14 season (larger positive number is better). This is the positive number of points that the player adds to the team by being "on" the court rather than "off" of it Per 100 Possessions.
GD --> +9.5
EB ---> +3.0
The difference there being 6.5. The difference between the two "positive net's" in the Individual ORTG - Individual DRTG was 5 (+9 vs +4). So, the Individual ORTG/DRTG in this instance was fairly on target, if only for this one example. Still, I'm sure On/Off and xRAPM are better or more exact measurements, or more useful.
PLAIN ENGLISH SUMMARY:* Dragic had a slightly negative effect for PHX's defense by being "on" the court in 2013-14
* Bledsoe had a slightly negative effect for PHX's offense by being "on" the court in 2013-14
* Dragic had a substantially positive effect for PHX's offense by being "on" the court in 2013-14
* Bledsoe had a substantially positive effect for PHX's defense by being "on" the court in 2013-14
* Dragic's positive effect on PHX's offense was larger than Bledsoe's positive effect on PHX's defense when each player was "on" the court in 2013-14.
Well I certainly don't doubt the conclusion that Bledsoe is a better defender being a Clippers fan and all, just saying that the individual defensive rating stat is a bit tricky because I think most people think it is team defensive rating when the player is on the court when it is actually just a calculation based on team defensive rating + how many "stops" (steals, blocks, defensive rebounds + non statistical stops) a player gets. The obvious flaw (which Dean Oliver knows of course) is the assumption that every player contributes equally to non-statistical misses and turnovers. So basically it is saying if all players contribute equally to that, then the guys who have the best combination of steals, blocks and defensive rebounds are having the best defensive impact (which obviously we know isn't actually true, though it can be). That is why big men almost always have the best individual ratings on a team, and why a guy like Boozer has a great defensive rating (team defensive rating is very good), and per 36 Boozer gets 8.3 DREB, 0.9 stl, 0.4 blk.
Individual Defensive rating is calculated as:
DRtg = Team_Defensive_Rating + 0.2 * (100 * D_Pts_per_ScPoss * (1 - Stop%) - Team_Defensive_Rating)
The higher the stop%, the lower the rating, and obviously the lower the team DRTG, the lower the number. In calculating Stops, you have stops 1 and stops 2.
Stops1 = STL + BLK * FMwt * (1 - 1.07 * DOR%) + DRB * (1 - FMwt)
FMwt = (DFG% * (1 - DOR%)) / (DFG% * (1 - DOR%) + (1 - DFG%) * DOR%)
Stops2 = (((Opponent_FGA - Opponent_FGM - Team_BLK) / Team_MP) * FMwt * (1 - 1.07 * DOR%) + ((Opponent_TOV - Team_STL) / Team_MP)) * MP + (PF / Team_PF) * 0.4 * Opponent_FTA * (1 - (Opponent_FTM / Opponent_FTA))^2
FMwt is forced misses, the issue we have here is that forced misses are estimated based on the team forced misses. So like mentioned before, it assumes that every player on a team forces an equal amount of turnovers and misses not accounted for by blocks and steals. You can see that stops are based on team stats except for steals, blocks and dreb.
The core of the Defensive Rating calculation is the concept of the individual Defensive Stop. Stops take into account the instances of a player ending an opposing possession that are tracked in the boxscore (blocks, steals, and defensive rebounds), in addition to an estimate for the number of forced turnovers and forced misses by the player which aren't captured by steals and blocks.
This is in contrast to team defensive rating which is:
Team_Defensive_Rating = 100 * (Opponent_PTS / Team_Possessions)
Calculations can be seen here:
http://www.basketball-reference.com/about/ratings.htmlSo yea, not saying your conclusion is wrong, but it isn't right because of defensive rating. Since they are on the same team, the difference in their defensive rating is:
Bledsoe (stls + blk = 1.9), dreb = 4.1, 106 Drtg
Dragic (stls + blk = 1.7), dreb = 2.3, 109 Drtg
Frye (stls + blk = 1.5), dreb = 4.2, 107 Drtg
