I am trying to understand "Why this is Such a Big Deal" ? Two guys of simlar size make contact and battle for less than 20 seconds ????
Dude it's just a fun spring football drill to get the players excited and hit each other. The average football play is 5 seconds, why would they make contact longer than that?
Similar size because they match up OL vs DL and some LBs, RBs and TEs, vs LBs and some DBs, WRs vs DBs.
Don't get why you don't think it's a cool drill. Just a drill that let's the players hit each other and compete. That's all.
