I don't really blame the team from a process standpoint. They addressed the issue by grabbing Irv Smith to fill the Hayden Hurst role. On paper, that should be fine.
It just hasn't worked out. Sometimes free agents miss. It's clearly a hole right now though, and I wonder if there are two viable solutions (not great, but viable) already present that have been left under the rug because of Irv's presumptive starting role. Both Hudson and Wilcox could provide at least what Smith has provided so far, and I suspect they could do better. Last season when Hurst was out, Wilcox did a nice job. I think he could be the tight end version of Trenton Irwin given an opportunity.
