Don’t like it. Easily identifying a player’s general position at a glance was handy. And 280lb edge “linebackers” wearing single digit numbers look silly.
Considering the number of "hybrid" players/positions in today's offenses (RB/WR, WR/TE, H-Back/TE, etc.) it makes sense they would share the same number ranges. Some of the numbers will definitely look weird for awhile though.
