Fix the salary formulas, or rebalance the engine, or fix the problems in 2-3 and you've got a winner. Giving up and just eliminating the tactic overall is a loser.
I've always said that the problem is deeper than just improving SB and fixing 2-3. Right now OD suffocates 3 point shooting and until that end of the equation is also fixed I predict outside offenses will remain dinosaurs in BB. Top division bigs shoot 55-65%. SB will help decrease that but the guards are all still shooting 30-38% with low 3-point %'s. Top division in Canada didn't have a single player shoot over 30% from the arc last season with a decent # of attempts.
That could easily be fixed in the salary formula too, though. Make OD for PGs as expensive as it is for a SG for a start and suddenly those high OD/PA guys are getting their salaries jacked up just like the high JS/JR SGs. Maybe reduce the cost of JR (and improve the training speed) so you're not stuck with guys with 12 or less JR going against a wall of 18+ OD with the inevitable result. And all they really need to do to make 2-3 much more effective is have the inside guys have their ID rather than OD defend passes down low as well in the 2-3 - because the fundamental problem is how easy it is to generate uncontested shots. Add in some general tweaks like maybe shotblocking leading to drawing a lot more offensive fouls on penetrating guards, low handling/driving maybe leading to open big men muffing the ball when it's dumped to them much more frequently, and perhaps you peg LI back some. Maybe bump up the shooting percentage slightly on uncontested jumpers and threes for skilled players, and lower the effectiveness of OD against JS/JR by including SB into the calculation (so a high OD/low SB guard would be great at pressuring, but easier to shoot over than one with balanced OD/SB). You'd need to have pressure train SB too, and of course some of these ideas would likely be painful initially, but they're all alternatives that are better than just removing LI, and then eventually LP, and if people ever figured out how to build effective II teams that too.
