Brad's one of the top coaches in the country period. I put him top 5 along with Popovich, Coach K, Calipari and whoever else you want to toss in there.
He improves his players, enhances their value and gets the max out of team in terms of wins/losses. His team plays hard for him more often than just about any other team in the league, which means he has the players respect.
I think he's also going to help with free agents moving forward. Guys will want to play for him, which may help tilt the scale, everything else being equal.
