Take this for what it's worth, but ESPN.com's Kevin Pelton ranks the Wolves' acquisition of Kevin Martin as one of the worst deals of the summer in the NBA:
Kevin Martin to Minnesota Timberwolves (4 years, $30 million); Jose Calderon to Dallas Mavericks (4 years, $29 million)
Group these two together because they represent a similar issue -- four-year deals to players on the wrong side of 30. Martin will be 34 and Calderon 35 in 2016-17, the final season of their contracts. Already, Martin and Calderon are among the worst defenders at their positions, an issue that should only be exacerbated by the aging process. Can they hold on long enough to justify escalating salaries? Consider me skeptical.
He makes a valid point about defense and age, but when a team hasn't had a legitimately sized shooting guard -- at least one who can actually shoot -- in forever, there is little room to quibble. The Martin signing was a good one from where we sit. Consider us less skeptical.
