I like Cordy Glenn, I think he's a solid Left Tackle, not a superstar but a very good left tackle. That being said, in a few years he's up for a new contract and Left tackles earn a lot of money.
This year is shaping up for some really highly rated Left Tackle Prospects falling to #9 given the 3 QBs going off the board before us. This got me to thinking that drafting a LT would allow us to shift Glenn to RT (where we clearly need an upgrade). This would ensure a solid LT for the next 4years at a low cost and would mean that Glenn would costs us 2-3M less to keep. If the kid we draft doesn't pan out, we simply move Glenn back to the left side.
Myself I'd jump all over Sammy Watkins but I doubt he drops to 9 and given I am a BPA proponent, i have found a way to justify it in my mind.
