I think Milt Stegall is carving out a niche for himself on the CFL panel. The curmudgeonly guy who calls it as he sees it.
Sanchez is improving, playing off of Milt's bad cop routine.
Matt Dunigan should be building on his QB career to be the analytical guy. If Matt can't step into this role, then I think they need an analytical guy like Lapo on the panel on a regular basis.
@Diggler67 I think the panel would benefit from an ex-ref, too. There are ex-players, ex-coaches, career broadcasters - but no retired officials that I can recall. Maybe Foxcroft will get an interview for his retirement, but that's about it. Having someone on there regularly could really improve the public perception of the officiating, and that perception definitely needs all the help it can get these days.
@khird On the panel, or even in some other capacity, e.g. available to comment on calls during marquee games. Maybe FNF doubleheaders or something like that.
