Shon Coleman was Hue Jackson’s first choice to succeed Joe Thomas at left tackle for the Cleveland Browns. Judging by his comments earlier this week, offensive line coach Bob Wylie also felt that way.

Unfortunately, Coleman proved beyond any reasonable doubt in the first week of training camp that he is not up to the task. Midway through Wednesday’s training camp session, Jackson and the rest of the Browns coaches had seen enough of the experiment.

Left guard Joel Bitonio took over at left tackle with the first team. Second-round rookie Austin Corbett slid into Bitonio’s spot at left guard. Coleman was relegated to the second team at left tackle.

We have no idea if the Bitonio experiment is permanent. Right tackle Chris Hubbard, who has looked solid (read: a lot better than Coleman) in pass protection in the three days of camp I’ve attended, is another option. He played some left tackle for the Steelers. Bitonio was a left tackle in college. So was Corbett. So was Spencer Drango, who filled in for an injured Thomas last season too.

Coleman himself probably still factors into the equation, though at this point moving him back up to starting status seems to be multiplying by zero.

I watched Coleman intently in the Sunday and Monday practice sessions. No matter who was lined up across from him on defense, from Myles Garrett to Nate Orchard to Chris Smith, continually beat him with the same basic move: get low and get around. Coleman’s utter inability to bend low enough or fast enough to stop it was both obvious and scary.

Now in his third season, Coleman has essentially blown his big chance. He wasn’t very good at right tackle in 2017. The hope was moving him back to the left, where he played at Auburn, would unlock the potential the Browns saw in the third round of the 2016 NFL Draft. Instead, Coleman was overmatched and unable to adjust when rushers kept racing around him with the same basic moves.

The knee bend, the foot quickness and the ability to swiftly shift his weight in reaction to the action simply aren’t good enough to start. The Browns now must decide if it’s worth keeping Coleman as a reserve on a line where depth is already a pressing issue based on what we’ve seen in camp.
