I think at the end of the day (season, postseason, etc) what we're all interested in is actual performance. Did they play well, did they win? Given that structure only tells us what might be, and many other things dictate what actually is (I swear I'm not trying to be a jerk, genuine interest) I have to ask why you focus so much on structure.
Structure usually tells...what you can do....it's not a surprise to me, that Fox is a sturdy...and powerful player...even tho he wasn't drafted...same with Westbrooks...same with Donald...same with Brockers...those guys...when looked at collectively "look" like powerful football players...adding in some measureables like speed and strength...you have a package.
Fox played well....it's a reason...part of it is his natural strength and power...which his body shows he's built for...
Like I say, you can't always say always...and never say never...but I rarely see little legs, or skinny arms..or vice versa....WORK...in the NFL.
You draft for a...a type...OL's should look like this...DL"s should look like that...QB's should look a certain way...RB's should....you also put into consideration their play...with lower round guys, guys that have played against inferior opponents, you have to project performance...because they haven't played against a bunch of NFL talent...probably none.
No team is gonna be built on a bunch of guys that were excellent in college...or played lights out...after round 3...you have to project...the best way is physical appearance....then measureables....and try to coach these individuals up to fill out a 53 man roster...
Hey man....I like questions...never look like a jerk with any question....some of these guys in here try to "stifle" real discussion....if you don't go with their narratives, you're the enemy...nope not me...I like explaining or trying to clarify where I'm going with a thought...so some can understand...I've played, coached, and watched a bunch of football...I've watched the Rams since the 70's.....I've SEEN better Rams players benched for lesser players since 1975 and wondered, "why?" James Harris being the first....
Watch the game...notice who does what play in...play out....rewind is your friend...
Matter of fact, I was watching the NO v Rams game...just the 1st Quarter.....and I saw a bunch of stuff...just in rewinding...and watching...I could bust a bunch of reply records...but, I'll just let the season play out...
now...onto these other guys....I got a bunch of...shall I say...replies to get too...LOL
