We need all hands on deck to win Games, winning Games is the most critical thing, that and playing crisper, more fundamentally sound Defense.
We have to change the "old 1980s &90s" mindset, when you step up and start Recruiting Serious FB Players with NFL Potential, then RS'ing means next to nothing.
Other than QBs, when is the last time you heard Ohio State, Oklahoma University, LSU, Bama, UGA, Clemson, ND, make a big deal or sweat the details over RS'ing any position players, that weren't injured?
ans:
Maybe 20 years ago(?), if a player can help he plays, period, hard stop, end of story.
If the Players pans out he's gone to the NFL after his RS-Soph or RS-Jr season anyway, and you never get that 5th Senior anyway, that's philosophy #1.
Philosophy #2 is this, more and more HS players are getting higher level instruction and development before they get to college, they lift year round, they only play 1 Sport in HS, so if you are recruiting the Players with the right Talent level, you'll have a pipeline of Talent to make up for Players leaving.
An example of #2: would you rather have our 5th & 6th year Seniors playing OLine or would you rather have the "backup" T-Fr & T-Sophs at a ND, Ohio State, OU, if you had to win a Game this season?
In summary, "getting old" is paying less dividends than it did back in the 80s & 90s, in 2021 simply get better FB Players that are more Athletic and better overall Athletes.
