Interesting idea.
I'm not a big Varejao fan. He's always a whiny little bitch like he's in a contest with Dirk Nowitzki for the league's Biggest Cry Baby award. But his height and hustle could help in areas.
I watched AK single handedly win tight fourth quarter games last year. I don't understand the outright resentment of AK here. You may not like him or his contract, but give cred where due. Andre wins games. He's extremely crafty, and was often the answer to those famous Jazz droughts. He's not a pure scorer, but he knows how to get to the line. The Jazz need that when they disappear on offense for 4-5 minute stretches. How many times did we see that last year in the fourth quarter? Over and over and over. Then AK shows up, gets the ball high, musters up some awkward looking drive, gets fouled, and breaks the scoring drought. Also, drawing fouls and creating foul trouble substitutions is a huge deficit that the Jazz just don't seem to understand. They could use a little more awkward AK foul flailings early on.
That said, Mo, as a pure scorer, could fill AK's role here much better. Plus the Jazz desperately need a competent backup for Deron. They absolutely fall apart when he's resting.
I'm also not big on filling up on AV's 8.33 m for 4 more years.
