A GM should always be seeking to improve the talent on his team; with a focus on the team becoming a team that can win more and more. The end of the roster shouldn't be throw-away spots, but lottery tickets (developmental, vet culture guys, single-skill guys, etc). Valentine is none of those.
Guys they could've gone after instead: Svi, Servydas, James Ennis, Hutchison, Mathews, Gerald Green, etc.
Svi - Team showed interest he didn't want to come here.
Servydas - Has shown nothing in the NBA for Pistons and sucked in SL for Pistons.
James Ennis - Is likely waiting for a end of the bench spot on a contender he's old now.
Chandler Hutchison - Is same as Denzel Valentine. He's not developmental. He's not a vet culture guy. He has no skills.
Garrison Mathews - Cavaliers have shown interest but Mathews may not want to come here per reports.
Gerald Green - Really?
