Per @InsideBirds there is a high probability the Eagles will take a WR in the 1st, but they could go offensive line or defensive end if one of the top players drop. @caplannfl also mentions the Eagles really want to get more picks after Slay trade.

Caplan “knows for a fact” that the Eagles like Justin Jefferson
Mosher: per source, he’s like Nelson Agholor but *way better*
Primarily slot, but can win outside with length, catch radius, and contested catch ability. Comps to Keenan Allen

Aaron Moorehead and Montae Reagor, Jalen’s dad, were teammates on Colts. In their personal opinions (read: not a source/report), Caplan and Mosher think the Eagles would pick Reagor over Jefferson.
