He was blunt in his assessment of the team and. Arizona Cardinals head coach Kliff Kingsbury told reporters that J.
Watt was "very limited" in his return to practice ahead of Monday's wild-card game against the Los Angeles Rams. The Steelers could be receiving some receiving reinforcements for the postseason.

Tom Brady. Aaron Donald. Cooper Kupp. Jonathan Taylor. Travis Kelce. Further study led to the launching of the bulbous bowed battleship Delaware in But it took another two decades before the bulbous bow really made a splash.
It came with the launch of the German passenger liner Bremen. The Bremen was the most technically sophisticated, and fastest, ship of her day. Designers took notice. Six years later, the French liner Normandie , also with a bulbous bow, managed to reach an astonishing cruising speed of over thirty knots. Her rival, the British Queen Mary , achieved this same feat without a bulbous bow, but it had a much larger engine.
After all, how could an odd appendage help a ship move faster with less fuel? Even as the mathematics matured, it still had to be validated. Before computers that meant experimentation — building and testing physical models large and small. The arrival of computers opened the door for computational testing.
Today, virtually every large oceangoing ship is designed with a bulbous bow, leading to fuel savings of about fifteen percent.
When a ship with a bulbous bow is moving forward, water flows over the bulb and creates a trough behind it. This trough reduces the wave generated by the edge of the bow. A smaller wave means less energy lost to the water. At lower speeds they have little effect. Ever new shapes are being designed and tested.
