I dont get whats happened with Howland. How could a guy have such a huge level of success and then totally drop off the map... all without a major scandal and with it taking place at one of the easiest programs to succeed at.
Way too long to try and explain and there is no one answer but IMO Ben forgot who he was. He got to 3 Final 4's with tough defensive minded teams. He felt like he was outgunned but look at who he lost 2, a repeat Florida team with 3 lottery picks, and a Memphis team where all the starters were in their 20's and had played together from prepschool on except for the best player, Rose, who was also ineligible. howland could have won an NC any of those 3 years but he also didn't coach well in any of those losses especially Memphis.
So he decided he needed to pursue a different type of kid, more offensive minded, he believed he could teach them to defend. Talent was down on the West Coast so Ben started trying to go after national kids and didn't get them, and he took local kids that he wasn't all that familiar with and got burned. Drew Gordon being the primary one.
for me in the end he started taking chances because his personality drove people nuts so he eroded the recruiting ties. That's why UCLA was recruiting Renardo Sidney, that's why he let Love's dad dictate who UCLA could take with Love. That's why he promised Holiday he'd play PG assuming Collison would leave etc. All that came back to haunt him.
Some of the kids he did get like Gordon and Nelson were huge problems that he should have seen coming or dealt with quicker but he felt he had to take those risks because he couldn't get the players anymore.
The last class to me was really nothing to do with Howland. UCLA got a very unusual situation where 4 kids had talked about playing together, 3 of them in particular(Kyle, Jordan and Tony) and it actually happened. They saved Ben's job for one more year but even last year it was obvious how much better the team played once the rumors hit Howland was going to be fired. It was like the team saw the light at the end of the tunnel and played better because they knew he wasn't coming back.
Too many things to say just one but for example when you watch Kawhi Leonard, Derrick Williams and Paul George, all 3 of those kids were in Howland's recruiting base the same time, and Howland didn't want any of them. He wanted the Wear twins, had a great relationship with their dad and they still went to UNC. So he took Nelson and Lane and Moser. People say the 08 class killed him and it did, but misevaluating the 09 class did him in too. He missed on 3 NBA first rounders 2 of whom were literally in his backyard.
