TL/DR, I'm sitting on Lamar, Daniels, Penix. Need elite young receiver. Thinking of trading Lamar for 1.03 to get Tet or Hunter (we have IDP). I think I'm safe getting rid of Lamar and riding Daniels with Penix as backup. Thoughts? 

Rest of the details...

First dynasty league and I admittedly joined without much research. Picked up too many older players. We are a year and a half in (started midseason), I finished 4th last season but was in first place all season, just had some unlucky breaks in playoffs. 10 team, not super flex, no TEP, IDP, 1 PPR, running backs get 0.5 points per carry so I went RB heavy in my draft but I'm hurting for WR. RB I've got Achane and Bucky and serviceable backups like Brian Robinson and Swift.

Beginning of last season I had trash for QB, I think Cousins and Tua. I drafted Daniels and Penix, but then traded for Lamar before the beginning of the season. Love Lamar and the guy I traded also had Mahomes.

Now I've got 1.07, no second round pick, and I need elite young WR(s). My young receivers have been a let down, Aiyuk, Addison, Tank. Drafted Jalen McMillan, Troy Franklin, and Malik Washington last year. Been relying on vets like Tyreek, Diggs, Thielen, Kirk. Looks like Egbuka would fall to me, and I can probably wait a year or two for him to break through Evans/Godwin, but would prefer the tier higher at Tet/Hunter. Maybe grab a RB at 1.07.

Assuming my league mate takes the trade, is this a good idea?

Should I offer this?
