Cover 1 did a nice breakdown of Hollins' game. He will bring more to the table than Sherfield did, but that said, he's not WR2. He does have a knack of giving QB's someone to throw to in a pinch. Check out the Cover 1 video. He's a good pick up. But we need WR2.
Burns is a good example. I'd rather extend Groot now than let him hit the open market. Snap percentage is a interesting point. Groot is mid 50's percentage wise. I wonder if he views it as a bonus as it prolongs his career and keeps him fresh for more effort in his snaps -- or if he thinks it's holding him back from better sack totals and higher value?
Extend him. Elite at setting the edge, run stopper and developing nicely in the pass rush. He reminds me of Phil Hanson. So not a game wrecker but all-around great DE.
Far from insane...
He swallows up two blockers and is dominant in the run. Before he was hurt, started penetrating and impacting the QB. He allows Oliver to be Oliver.
"..and then one day the rain came and washed all the crops away..."
I get it, but eventually you have to make good on what you spend. It's not monopoly money.
