One question to ask is, given the history of the existing &#x27;unnecessary roughness&#x27; &#x2F; &#x27;illegal hit&#x27; rules (which have been around for decades), why haven&#x27;t teams been incentivized to &#x27;draw the foul&#x27; already? (in the nfl, faking an injury at critical times is already disincentivized, see <a href="http:&#x2F;&#x2F;static.nfl.com&#x2F;static&#x2F;content&#x2F;public&#x2F;image&#x2F;rulebook&#x2F;pdfs&#x2F;7_Rule4_Game_Timing.pdf" rel="nofollow">http:&#x2F;&#x2F;static.nfl.com&#x2F;static&#x2F;content&#x2F;public&#x2F;image&#x2F;rulebook&#x2F;p...</a> section 5 article 4 page 18)<p>Also given how much time is spent going over videos of games after the fact (at all levels from high school on up), someone trying to draw the foul stands a pretty good chance at being caught out at it, which opens them up to, say, getting a multi-game suspension.
