I really don't know much about Randy Wittman's coaching philosophies, but i think McHale has assembled a team that can really get after it in transition and could suprise a lot of teams this year with that ability.
A starting lineup of Foye at PG, Brewer at SG, Miller at SF, Love at the 4, and AJ at 5 would really give teams hell if they were able to push the ball. I know a lot of people have questions about Foye coming off that injury, but he actually played pretty well towards the end of the season averaging 14/4 while shooting 42% from the field and 40% from 3. Brewer won't scare anyone offensively, but he loves to get up and down the floor and get to the rim - the addition of Miller will partially make up for Brewer's shooting deficiencies. Speaking of Miller, the guy is just a gamer. He's never had the chance to play on a good team, yet consistenly brings the effort to the table every night. Just the prescence of him on the floor will give love and AJ enough room to use their McHale-esque post games. AJ may not be the best up-tempo big man, but if he commits to it he can certainly beat the opposing teams 5 up and down the court. Love's uncanny outlet passing will be a huge asset to this team if they commit to this style.
The only question i have about this team is their post defense - and it's a big one. Foye and Miller will hold their own while Brewer will give opposing 2/3's fits, but Love and AJ are too undersized (esp. in the western conference) to do it alone. Calvin Booth and Jason Collins are adequate, but both are a liability on the offensive end.
In the end, i think McHale did a great job adding Miller and Rodney Carney, as both will really help the development of AJ and love down low, but they won't be winning a lot with their two bigs taking a beating by guys much bigger every night. Jefferson will hold his own offesnively, but trying to bully the Chandlers, Shaq's, and Yao's of the world will really take a toll on him. And love trying to cover Duncan, Stoudamire, or West? I don't think so.
