UL challenges

How long do you think it would take to get all the tokens needed to get the full UL?

Couple hours straight. It's such an easy grind, just tedious. Take the token pack, unless it  you are going for the UL oline chem, then you want to grab a couple of the BND player packs. But if that doesn't interest you, always take the token packs from the week's final challenge.

Edit: the BND player packs give you two player cards of that week's LTD players, but they are a much lower OVR. For example, this week's LTDs included Larry Allen (RG). If you take the BND pack this week, you will receive a lower OVR Larry Allen that has UL chem that you can use as a backup in your Oline. You need 8 UL chems for the UL oline boosts.
