What's the problem with going prostyle in youth football?  I know coaches are using a lot of spread because that's what the high schools and colleges are doing.

  Is it because youth football is rarely won through the air, in which case run heavy systems (wing T, singlewing,etc.) make much more sense?

Fifteen years ago, it seemed prostyle was the most popular offense on every level. 

I think if you have no passing game, there are better options.  But if you can coach up a passing game to go with a simple running game, the prostyle can really move the chains even without a lot of speed.

Do prostyle teams ever make any noise in national championships in Florida?

I'm definitely no expert on youth football, just curious how coaches get into coaching the schemes that they use.  And why so many have gone away from the prostyle offense.

Most youth coaches can't coach the zone running game. Most youth coaches can't coach a good passing game. You do see it at nationals.

I'm never sure what people in this section mean by "pro style".  The core offense of the Warrior club when I started coaching them was split back pro, part of the pro style I understood from the 1960s.  I find it eminently suited to youth, although not my preference.

Today I think many, possibly more, coaches mean something that's essentially an ace version of common I formation offenses, with the running game simplified down to a single runner finding holes w zone blocking in front of him.

We discussing one of those here, or both?

We have always had a pro i look in are arsenal and it has always worked for us as a complete series, Toss Sweep, Fb Ctr Trap, Toss pass, Iso, Dive, Ctr, Ctr Boot , and some 3 and 5 step concepts . With a very easy blocking scheme attached ti that i learned from Jack Cochran a local legend. This guy won 7 state title running those very basic 10 plays with 3 formation's and that's it. I've always keep in our back pocket for when the slow our WT down and gang up on our wing. Because of the down hill nature of it. It really has been a great change up for us and has allowed us to roll up some big numbers in certain years.

Pro Style I is a great base for Youth.  Easy to go from a Power Game:

XTGCGTZ
......Q
.......F...Y
.......R

To an Open Offense . 

X......TGCGTY...
............Q.........H.......Z
.
............R 

Its no different than any other offense if you remain within the scheme and expand as kids develop.  It ALL about how well you can teach it. 

Coaches,

I dont think this is about prostyle or any system for that matter. Whichever system you chose to use keep it simple, you can use any system and over complicate it, the better coach is the better teacher!
