Backup PG candidates

Who should the Cavs go after? FA or Trade?

"CLEVELAND CAVALIERS – Current Record (27-8) / Since Last Time (8-2)

Resolution: Get a viable backup Point Guard
The Cavaliers are sitting pretty atop the East and should cruise into yet another playoff (and finals) series. However one could argue that whilst the Big 3 are as good as they have ever been as a combo, the complimentary pieces are not quite as good as years past. Injuries strike (Liggins has stepped up for JR) and veterans fade (can R-Jeff keep it up & will Dunleavy join him?) putting pressure on your depth. But PG depth is already a concern and the Cavs need to work a trade or strike FA gold to sure up their second unit. Speaking of trades, Kyle Korver is now a member of the Cavs. Not a back-up point, but he’ll do."
