Intense training now is ok before the season starts, but when you play a game you lose energy. If you train intense you only get 3 points increased every day. Normally you lose around 10-20 energy points and there are games every 2 days so you only get 6 points back if you train intense.
If your energy is low the chance of getting injured increases, so generally you want to be 96+ energy before the game.

Georgepir summed it up good. The only drawback to Intense training is that you don't gain your energy back from a game as quickly.

You NEED atleast 95 Energy Points for a game, or else your playing ability is going to be rather poor.

So you want to trade intensely as possible, but with respect to making sure you have full, or near full, energy. Some players use little energy when playing, and can play quite a bit without tiring, and can train harder. Some can't without significant boosts to stamina.

Just made a lvl 4 WR and a lvl4 DT, maybe we could get them to be part of the team?

okay i got my WR set up and gave him some nice gloves

So I have upgraded the SS to level 6 and tomorrow when the new season begins I will upgrade him to level 9. He will be a lvl 10 in a matter of 2 days and then a force to be reckoned with in defense.
Also I will upgrade the lvl 4 WR and NT to lvl 7. Hopefully this can help the team a bit.

wow i'm surprise I never saw this thread before ....big NFL fan here I'll get started soon !

 great! There is an opening for a starter in the ROLB position if you are interested. You could just use the referall link that is provided in the OP. 

'fraid not, my boy is taking the ROLB when the trade goes through.

Oh sorry, didn't know bout that.
Probably I should just let mrstickball do the talking :D

Bladeneo is right.

However, we only have 1 LB as a backup. We still need an extra Free Saftey, and desperately need a #2 Tight End.

But outside of that, those are our NEEDS. We can always use another WR, TE, O-lineman (minus center), and nearly every defensiveman we can get.
