The XFL is not going to sit around and let the USFL get a spring football foothold.
From ESPN:
The XFL continued its efforts to counterprogram the USFL’s return to the field by convening a virtual meeting of agents Monday night to pitch them on the league’s plans for 2023 and beyond … The XFL’s top football executives — Marc Ross, Doug Whaley and Russ Giglio — told agents that the XFL would offer higher salaries and better benefits than the USFL.
Ross, Whaley and Giglio also suggested that the XFL’s season schedule, which will begin in February and end in May, would be more “advantageous” for players who want to get subsequent consideration from NFL teams.
