Chrissy McKaigue is by common consent the best full-back in Ulster right now.
And Derry manager Brian McIver certainly has reason to be grateful for this as the Kilrea clubman will be handed an important role today. He will be expected to curb the input of free-scoring Cavan full-forward Martin Dunne when the sides meet in an All-Ireland qualifier at Celtic Park.
Dunne has been a revelation in the Cavan attack this year, having announced his championship arrival by scoring nine points, eight from play, in the Ulster preliminary round defeat of Armagh.
McKaigue, who shared in Ulster's inter-provincial triumph earlier in the year and has since worn the Derry No 3 shirt with distinction, is the rock on which McIver has built a resolute defence into which Dermot McBride has slotted once again following a lengthy lay-off because of injury.
While McIver derives satisfaction from the qualifier wins over Sligo and Down to date, he sees Cavan as a major threat to his team's chances of further progress.
"Cavan have shown that they have real quality in their attack and they will come to us in a good frame of mind following their win over Fermanagh last weekend," observes McIver.
While Dunne has been on fire lately thus vindicating the faith that manager Terry Hyland has shown in him, Eugene Keating and Cian Mackey have also been very much to the fore in the Breffni side's recent surge.
