With the first week of NFL free agency now in the books, I’ve offered a dozen Ravens thoughts, each in 50 words or less:1. I like the Michael Crabtree signing, but looking at past notable receivers’ first season with Baltimore is concerning. Derrick Mason, Anquan Boldin, T.J. Houshmandzadeh, Lee Evans, and Jeremy Maclin all saw their catch and yardage totals fall from the previous year. Steve Smith and Mike Wallace were the exceptions.2. Benjamin Watson signing with Kansas City would put the Ravens in line to receive a 2019 third-round compensatory pick for Ryan Jensen. These comp choices shouldn’t drive the entire offseason, but that’s a pick too valuable to pass up to sign any unrestricted free agents remaining on the market.3. Watson’s potential exit reiterates how big a need tight end remains. I’m not enthusiastic about anyone remaining on the market, but history suggests counting heavily on a rookie is a big mistake. This position may simply remain a question, but an early draft pick would bring enticing upside.4. The reported visits of restricted free agents Willie Snead and Cameron Meredith reflect the desire to further address wide receiver, but structuring an offer sheet is tricky. You don’t want to exhaust too much effort when you may just be negotiating a deal for the original team in the end.5. Declining the option on Austin Howard cleared $3 million in cap space, but was it wise to part ways with a reliable starting right tackle for only moderate savings? James Hurst hasn’t fared well at that spot in the past and Alex Lewis is a complete unknown there.6. Jensen becoming the NFL’s highest-paid center is a reminder that incumbents can get markedly better over time and late bloomers do exist. There’s still at least a glimmer of hope for the likes of Breshad Perriman, Kamalei Correa, and Bronson Kaufusi, even if the Ravens aren’t banking on it.7. It appears Brandon Williams’ eye disorder is under control, but that’s still not something you want to hear about for anyone, let alone one of your best players who just received a lucrative contract 12 months ago.8. I’m interested to watch Tim White and Quincy Adeboyejo this summer, but I still see some fans putting too much stock into small glimpses of promise. We’ve seen this movie before, and the Ravens shouldn’t expect any of their young incumbent receivers beyond Chris Moore to make the 2018 roster.9. Wink Martindale attending Derwin James’ pro day garnered attention, but a team needs to be sure any prospect — not just James — praised for athleticism and being able to line up at multiple positions will truly excel at at least one spot before using such a high pick.10. Ryan Grant wasn’t going to get the same deal elsewhere after failing Baltimore’s physical, but a one-year, $5 million deal with Indianapolis is such a drop-off that you wonder if others had concerns about his ankle. I feel for him, and this still wasn’t a great look for the Ravens.11. Eric DeCosta hasn’t been made available to local reporters since Steve Bisciotti announced the longtime assistant general manager would be taking over for Ozzie Newsome next year, but he shared his thoughts on the pending change with the team’s website HERE.12. I’m amused by anyone believing the proposed language changes will fix the catch rule, but at least the league is trying to fix it. I can’t wait for those heated debates over what “the ability to perform a football move” really means.
