D-line. How many 1st Rounders does KC at WR? I'll give you a hint it starts with Z and ends in ero. We were able to turn a 2nd Round RB into the 4th leading rusher in the league. A 5th Rounder in Diggs has been amongst the best at his position. Look at the league leaders in receptions last year it's littered with WR drafted outside Round 1. By contrast look at sack leaders, at least half of the top 20 were selected in Round 1. Because pass rusher is more about pure speed, strength and athleticism. Where receiving is about route running, short area quickness and getting open quicker sooner than later and ability to avoid or strong enough to get off a jam. Why did the 49ers lose Sunday? Not because they couldn't score in OT but because they couldn't stop KC's offense in the OT.
