I kinda wanted to see what people think on this im usually not keen on starting a Fr if im going to be competing ..with that said im already starting a Fr at Sf

A stud basically (for my prestige) 
avg,low, High/High,High/High,low,low,High/high,High/High, avg,High?,High?
those last 2 highs im not sure if there high high or high low..dont remember those coming in my scouting reports. but as you can see basically is a stud lol and i have no other sf capable anyways.

On to the real topic

Brown 
avg,low,avg,high,avg,avg,low,high,low,avg,high    low D+ free throw
Overall looks like a decent player, okay ath,speed, bad reb good defensive player, score a few points and be solid with low to/assist ratio but horrible at free throws...

Or Alvarez A true freshman as well
avg,low,high,HIgh/High,high,low,High/High,avg,low,avg,high with a b- avg free throw

now as you can see another solid player in the making, also i run a fastbreak and he has a iq fastbreak c+, and man to man D+ which is what i run for d. Brown is b- both .

now do you think Alvarez is the better player/fit for my team or is brown, i think i like Alvarez better due to him being a better free throw shooter , and rebounder and prob a few more ticks on ath but the speed is what is making me weary i can only hope for a few more upticks in that as well.
Overall they both look to top around 770 or so
Again i do look to compete for  a NT bit not only this year but every year as well lol.

Thoughts suggestions comments?

I don't really think Brown is better than a bench player.  I can't figure out your list.  I think you mean that Jimenez & Alvarez are both HH in Def, but they both start too low in Stam.  Unless they are capped in Stam, then go ahead and start them and let them improve.

Yes both HIgh/High in def , and Alvarez is only avg stamina gain 

Yeah, I say start them at fairly fresh and let them improve.  You'll have to run normal tempo with that frontcourt stamina; too bad you can't run slowdown on occasion.

i only run fast fastbreak, and i dont use the fairly fresh, i get better results using approx minutes, u get subsutions more frequently it seems so guys are better off
