Least efficient bloating of salary I've seen since the days of uber-rental bigmen (400k+, though that was before the formulas got dialed way back to reward building super players more).
Honestly I don't get the HA/DR craze. I find them to be empty levels to a certain extent, as I've had relatively low HA players who don't turn the ball over regardless, and IS is starting to be favoured over DR when it comes to getting perimeter players to score, especially since the former skill is free in the PG/SG/SF formula.
If we ignore the financial side of things however, I don't think Boissard is that bad. Awkward defensively, but I daresay the french NT has underutilized him as taking the hit to inside defence does give you an SF with great rebounding for the position and an almost unguardable player on the perimeter. Of course I don't know what France actually has at the SF position, maybe they run deep there and have no real need for such an awkward build.
