Pro Football Focus believes Ronnie Stanley will make a big impact for the Baltimore Ravens

Pro Football Focus unveiled their Top 20 Offseason Additions Likely to Make an Immediate Impact. The Ravens first round offensive tackle checks in at a respectable ninth:

9. Ronnie Stanley, OT, Ravens

How he got here: 2016 NFL draft (Round 1, pick No. 6 overall, Notre Dame)

An injury suffered by Eugene Monroe left the Ravens reliant on 2014 undrafted free agent James Hurst last season at tackle. He was our 74th-highest-graded OT last season, giving up 41 combined pressures in just 358 snaps. Stanley was probably the best pass-protector in the 2015 draft class, and he’s a perfect fit in Baltimore’s zone-blocking scheme. Stanley possesses the quick feet and athleticism to cut off backside defenders in outside zone—he should make an impact in both facets of play.

Veteran cornerbacks Josh Norman and Sean Smith are the top two on the list, with defensive lineman Malik Jackson coming in third.  Stanley is the fourth highest ranked rookie, after Bills linebacker Reggie Ragland, Bengals corner William Jackson III and Cowboys running back Ezekiel Elliott.  In total, half of the twenty players selected are rookies.

The AFC North is well represented. In addition to Jackson and Stanley, Steelers tight end Ladarius Green came in 11th and Brown rookie receiver Corey Coleman 12th.  Two offseason departures from the Browns offensive lineman, Mitchell Schwartz and Alex Mack, were also selected to PFF's list of impactful additions.

It is surprising that new Ravens safety Eric Weddle is not projected to be one of their most impactful offseason signings.  Weddle is now 31 years old.  He may not have the athleticism and playmaking ability that he had early in his career.  But if he can sure up communication on the back end of the Ravens secondary, the Ravens will be thrilled with his impact on the 2016 season.
