Seahawks observations from Day 9 of training camp: Trevone Boykin shows his mobility

RENTON – One thing that undrafted rookie Trevone Boykin has going for him as he tries to secure his spot as Seattle’s backup quarterback is his mobility. Coach Pete Carroll has noted a few times that it would allow the Seahawks to run their desired offense – with all of its roll-outs and read-option plays – if Boykin ever had to step in.

Boykin’s time of 4.77 seconds in the 40-yard dash was second among quarterbacks at the scouting combine. He has shown that speed during offseason practices and during the start of training camp. He’s no Russell Wilson – no one is – but Boykin looked a lot like him during one play on Tuesday when he escaped a collapsing pocket by running around one oncoming rusher then beating several other defenders in a sprint to the corner of the end zone for a touchdown.

Boykin also made one notable play with his arm on Tuesday, dropping in a well-placed deep ball to wide receiver Uzoma Nwachukwu after getting cornerback Jeremy Lane to bite on a pump fake.

Thomas Rawls back at Seahawks practice; Jimmy Graham ‘really close’

Here are a few more things I saw at Tuesday’s practice, the Seahawks’ ninth of training camp:

• The offensive line was the same as it has been for most of camp, with J’Marcus Webb getting all of the work with the first group at right tackle after giving way to some other players there during one practice last week. Bradley Sowell again took some of the reps at left tackle for Garry Gilliam, who is coming off surgery to remove a cyst from his knee and is in his first year at that position. Jahri Evans worked with the second team at left guard, which was expected given what Carroll said after the team signed him over the weekend.

• Defensive tackle Brandin Bryant got the best of guard Mark Glowinski during a turn in the one-on-one pass-rush drill, getting him off balance and then tossing him aside. It was only one play, but it was nonetheless notable that Bryant, an undrafted rookie, overpowered what may be Seattle’s strongest offensive lineman in Glowinski. That drill had been the setting for a few skirmishes between Seattle’s offensive and defensive lines last week, but it again ended without incident Tuesday.

• Defensive end Frank Clark rushed from left defensive tackle during an 11-on-11 period in practice. He did some of that as a rookie last season. Carroll said then that he liked the idea of Clark rushing against a much bigger guard who may not be equipped to handle his quickness. But it wasn’t clear if the Seahawks would ask Clark to do that again this year now that he’s slimmed down and in line to rush more from the right edge with Bruce Irvin gone. It looks like that’s still in Seattle’s plans.
