For the part in bold: Did you see the ends of the last 2 seasons? Losses at home in the NIT.
For the underlined part: I felt the same as you, and even secretly hoped we wouldn't make the tourney, not only because I kind of thought we didn't deserve it objectively, but also because I thought a loss might lead to change. But, I think/hope we may be seeing a coach in evolution himself, and his system along with that. Pearl probably tweaked and modified his system in DII for years before he felt he had a good general formula for high success, consistently. Look at Amaker: mediocrity at Michigan, years developing the Harvard program and his system has led to two straight tourneys with wins in each. Is it possible that at Mizz St., Martin inherited talent, and their success then masked the fact that his system that he wanted to run was still being molded, and the same has been true here. We may have been seeing a team playing in a system that was constantly evolving to become better, and that has been what's led to the inconsistency we've been frustrated by and scratching out heads about.
At least, I hope. But, I'm certainly easing up on his, because the team seems to be responding to something right now, and the result has been cohesiveness, discipline, and resilience for more games in a row than we've seen before. And a Sweet 16 run will do nothing but help recruiting, which Martin has done pretty well, with Stokes and Hubbs, getting IIRC more 5* players than Pearl, and hopefully, we can get more of the 4* guys in the fold with these improving results.
So, all in all...Go Vols!
