I prefer those bottom roster spots are used for ST. You give the ST Coach priority to ensure he's got the gunners he needs and returners, as well as a small group of teams pros to mix in among the rest to make your units as competitive as possible.
Rams under McVay have always prioritized upside on the bottom of the chart. With the wideouts for example if you look at the group over time, year to year, I think it's clear they would have been better off ensuring they have teams professionals in reserved slots somewhere on the bottom of that chart. Some, like Skow, did a great job for us of course. But generally speaking I think one way McVay could be even better is by putting a little prioritization on teams. This is not a new thing.
I've been unhappy with our gunners, as well as the tendency of opposing gunners to be on top of our returner without much fight by our boys. Also we never try to find returners, it's always an afterthought. That role should be a dedicated roster spot. It is far more important for the team's chances of winning than your sixth or seventh wideout who has more upside but offers little to the teams room.
