Self subs Mason for Tharpe, but the lead does not narrow significantly.
Inference: Tharpe, despite his defensive limitations, was not the real problem.
The problem was not enough help from Wiggins and Selden. Both the freshmen wings were overwhelmed the first half by playing against guys as fast as they were and by having to defend without Embiid being healthy enough to cover THEIR defensive limitations.
If Self sticks with a limited Embiid, then the 4 has to take on a much greater defensive load of covering the freshman wings' mistakes and failures to help.
A healthy Embiid covered a multitude of deficiencies, but even Embiid could not cover up the defensive weaknesses of the freshmen wings against the LSAs of Florida and SDSU, much less when injured against Texas.
The gaping holes in this team's defense against the LSA teams are Wiggins and Ellis.
Ellis can usually guard his man, but he can't give help,or defensive rebound against these teams.
Wiggins often guards his perimeter man very well with and without the ball, too, and most games gives help on the perimeter, but having to give help inside exposes his softness. He doesn't know how to guard the blue meanies inside, and so doesn't give effective help there unless they are short, no talents.
Self defense requires a 3 fast enough to give perimeter help and feisty enough to help with the blue meanies inside. Brady and Selby at 6-3 or less could do it most of the time. But it took the talent of Rush and Releford to get it done against the most talented teams. Rush was tough enough to do it as a freshman. Releford needed 2.5 development years to master it.
Wiggins appears not able to do it for whatever reason.
Perry could be this kind of 3, but being more than a finesse 4 this season seems beyond him.
Until Embiid and Black get a lot better, or Traylor makes a nonlinear leap this problem is apt to surface against the LSA teams.
One logical step is to shift the 3 defensive role to Selden and have Wiggins play 2 and we saw some of that vs Texas the second half. It's a huge burden for Selden, but Self basically turned the offense over to Selden the second half and Selden responded well. Now Self must do the same with the defensive role, even though Wiggins ought to be more suited to it. Selden has the toughness now to play with the blue meanies. Wiggins appears not to. Wiggins could flourish outside and not be "scared" as the Texas player described Wiggins.
Moving Wiggins outside on both ends forces opponents to take ONE their of their LSAs away from helping in the paint, or Wiggins will run wild outside.
Go for it Bill.
